Q

What is a Search?

Jones / Physical trespass

A

Good ole fashion trespass to the things enumerated in the Fourth (persons, houses, paper, and effects) = search. Easy.

Jones = beeper on his car.

Q

What is a search?

Dog sniffs

A

If you/your stuff is in a place where the cop/dog can lawfully be, the dog can sniff it.
- Airport = no problem (Place)
- Lawful traffic stop = no problem (Cabelles)

  • Dog sniffing porch after no one answered doorbell = SEARCH (Jardines)
    — Even though normal people can come up to porch (cartilage) and knock, having a doorbell doesn’t invite a canine forensic investigation. That’s a trespass, and therefore, is a search under Jones.

Q

What is a search?

Katz test

A

In Katz, the Court made clear that a physical trespass is not essential to a 4A search.
Rest:
1. Government upended someone’s actual (subjective) expectation of privacy
2. The expectation is one that society recognizes as “reasonable” (aka recognized by the majority of SCOTUS as reasonable)

Q

What is a search

Katz analysis: if any random citizen could do it

A

Greenwood (trash on the curb)

Since any random citizen walking past could gave gone through the trash (it was abandoned property), cops can do it too. There is no expectation of privacy.

  • Police are not expected to “avert their eyes” from publicly observable criminal activity

Q

What is a search

Katz analysis: observing cartilage from the air

A

This falls in the Greenwood “if any random citizen could do it” theory.

Ciraolo (weed growing inside fenced cartilage)
- Even though the weed we within cartilage, that fact does not bar itself from public observation—anyone could have flown 1k ft above the house and saw it…
- The fact that one POV was blocked doesn’t prevent the officer to observe from a different vantage point he has the right to be.

Riley (greenhouse observed from 400 ft chopper)
- Court: helicopter was flying within FAA regulations, so anyone could have done it. No expectation of privacy if anyone could do it.
- Strongly suggesting that as long as pilots obey the law like FAA regulations, Katz will not prevent their observations

Q

What is a search

Katz: Third party doctrine

A

Anything given knowingly to a third party does not have a reasonable expectation of privacy because the third party could have handed over your stuff. (Smith v. Maryland)

Exception:
- location data given to phone company… (Carpenter)
Court afraid of the slippery slope. Not getting rid of 3P doctrine. Just not going to apply it here since the consequences would be so great.
Allowing this would open the gates to all texts, emails, etc.

Q

What is a search

Katz: Open fields doctrine

A

All “real property” is not protected by the Fourth. Only houses are enumerated. This includes the cartilage (area immediately surrounding and associated with the home), but not “open fields”

Q

What is a search

Katz: Open fields doctrine

How to define curtilage

A
  1. Proximity to the home
    - WAYYY more important than the rest of the factors (if you are far from the house, you lose (Dunn lost))
  2. Whether it is included within an enclosure
  3. Nature of use of area
  4. Steps taken by resident to protect the area from observation by people passing by

Q

What is a search

Katz: Sense enhancing technology

A

COULD the information have been obtained without the use of the technology and without trespassing on [thing enumerated in 4A]?

  1. if yes = no reasonable expectation of privacy
    Knotts beeper on meth ingredients to track car
    - Public roads mean police could have totally tracked you with their eyes if they were better at their job.
    - Why isn’t this a Jones trespass??
    - - Beeper put in ingredient tub BEFORE it was knotts property so no trespass.
  2. If no = definitely a search
    - Using sense enhancing technology to obtain information that could not otherwise be obtained w/o intrusion into a constitutionally protected area is a search.
    - at least where the technology is “not in general public use” (BT: what the hell does this mean though? prob just like “not weird” for someone to have it)

Q

What does probable cause have to do with unreasonable searches?

Q

Probable cause defined

A

Whether given the totality of the circumstances in the affidavit, there is a fair probability that contraband or evidence of a crime will be found in a particular place.

  • Fair probability (doesn’t require an actual showing). Not a high bar.

Q

Probable cause & the subjective opinions of officers

A

If there is actual probable cause, we won’t look at the actual subjective opinions officers.
So you can 100000% use probable cause on one crime to investigate another within reason.
- If you have PC that they are committing traffic violation, you can pull them over even if the real reason you want to pull them over is you think they have drugs.

Q

Warrants and searches

A

SCOTUS has repeatedly stated that searches without a warrant are presumptively “unreasonable” and accordingly are presumptive violations of the Fourth Amendment

Q

Warrants

Particularity requirement & why it matters

A

General warrants that do not specify the persons or things to be seized are prohibited by 4A.
- need some sort of specificity but don’t have to list exactly what it is.

This constrains where police may search.
- If searching for a stolen grand piano, police can look in any room, but can’t open drawers/cabinets (that would be unreasonable). If drugs were found when searching the cabinets that would be an unlawful search even though they had a warrant to search for the piano.

Q

Warrant Execution

Knock & Announce

A

Common law knock & announce rule is part of conducting a “reasonable” search
- Exceptions:
a. Under circumstances presenting a threat of violence OR
b. Reason to believe evidence would likely be destroyed if advance notice were given

However, the fact that a certain type of investigation may frequently present these circumstances is not enough to dispense with K&A in every investigation of that type (no blanket exceptions). Fact & circumstance based decisions must be made each time.

Q

Warrant execution

How long after knock & announce do police have to wait?

A

Depends on factors such as what the police seek, anticipated, dangerousness, etc.

US v. Banks found 15 seconds justified. Lower courts have approved shorter (CoMo 5 seconds)

  • BT doesn’t think the time allotted provides sufficient time for people to get to the door without being in harms way

Q

Warrant Execution

How must police treat persons present during the execution of a search warrant?

A

If a person is there (in house/curtilage), police can detain the person for the length of time that it takes to reasonably conduct the search, which is “surely less intrusive than the search itself”

Rationale/Justification
1. Preventing flight in the event incriminating evidence is found
2. Minimizing the risk of harm to the officers and
3. Facilitating the completion of the search (help unlock doors so we don’t have to knock them down)

Officers can then for sure ask detained person questions (they don’t have to answer)

BUT CAN’T
- Go grab you if you happen to have just left the scene before cops arrived
- Search the person detained absent separate reasonable suspicion required for Terry stop
- Arrest the person just for being present

Q

Warrant Execution

Mistakes

A

Police don’t have to be perfect when executing. If officers made a reasonable mistake, it can still be a reasonable search.

Needs to be some sort of boneheaded unjustifiable mistake to be unreasonable.

Q

Warrant exception

Plain view

A

Applies
(1) when incriminating evidence or contraband is discovered in a place where the officer has the lawful right to be (warrant, warrant exception, public place); and
- this means if warrant/warrant exception police need to be acting reasonable re: what they are searching for (think piano hypo)
- plain view exception doesn’t GET the police any place they otherwise can’t be.

(2) the officer has probable cause to believe the object is subject to seizure
- officer can’t pick up a stereo that looks like the one they know is stolen and flip it over (seize) to check if serial number matches.

Allows police to:
- Seize evidence in plain view without a warrant. Objects are subject to seizure if they are contraband or are otherwise evidence of, fruits of, or instrumentalities of a crime

25
Warrant exceptions Plain view rationale
If contraband is left in plain view and is observed by a police officer from a lawful vantage point, there has been no invasion of a legitimate expectation of privacy and thus no “search”
26
Warrant Exceptions Automobile exception
Applies if (1) police are lawfully next to the car; and - doesn’t get you TO the car, just IN the car. - If it looks like something that could drive away = automobile (2) have probable cause to believe something subject to seizure is in the car - as long as you have the PC necessary to get a warrant if there was a tiny judge in your pocket, you can search the car. Allows: - Police to search the WHOLE car. Including closed containers in the car.
27
Warrant exceptions Automobile exception rationale
1. The mobility of the vehicle — will lose the chance to seize if officers take the time go get a warrant 2. There is a reduced expectation of privacy in a car that makes it different than a home. it’s in public places all the time and under a lot of regulation.
28
Warrant Exception Search incident to lawful arrest (SILA)
**Analyze separate warrant exception for arrest as well** Applies if (1) there was an arrest made. (that’s it — anytime there is an arrest they can SILA) — the probable cause of the arrest is sufficient PC to conduct SILA w/o any additional evidence Allows - Search of person PLUS - the area “within his immediate control” (think, area from which he might gain possession of destructible evidence/weapon) - In a car, this would be like anywhere someone driving or riding int he car could get to without using tools. (no trunk, gas tank, etc.). If they want to search the trunk, need SEPARATE PC to then use to get automobile exception.
29
Warrant Exception SILA rationale
1. Safety of officers (disarm) 2. Prevent concealment or destruction of evidence (preserve evidence)
30
Warrant exceptions Consent
Genuine consent serves as a valid substitute for a search warrant. - Proof of knowledge of right to refuse is not required to establish consent, but can be considered in totality - Officers can rely on the consent of an occupant who shares or is **reasonably believed to share authority over the common area (even if they later find out they were wrong, still reasonable search)
31
Warrant Exceptions Split Consent
A physically present co-occupant’s refusal prevails. Any subsequent search is unreasonable (according to 60 y/o judge who lives with his mom in New Hampshire) - In absence of co-occupant, the consent of the physically present co-occupant is valid over absent non-consenting person.
32
Warrant Exceptions Exigent Circumstances list
1. Hot pursuit of a fleeing criminal suspect 2. protection of public safety from immediate threats, and 3. preservation of evidence from destruction
33
Warrant exception Exigent circumstances: Hot pursuit
Allows: - officer to follow a fleeing felon into a house and look around to protect themselves, find weapons, find suspect, etc. - even allows officer to search washing machine downstairs right after suspect was caught elsewhere When: Officers see someone commit a crime and then run into a house - Pursuit still hot if they get a “he went into that building” Rationale: - it would be dumb if criminals could evade police chase by running into a private house
34
Warrant exception Exigent circumstances: Public Safety
Allows - officers to exeter a home w/o warrant to render emergency assistance When: - Police believe public safety is at immediate risk (911 calls; person in need of medical aid; hear screams; protect from imminent injury) Rationale - Need to protect or preserve life or avoid serious injury - Absent this exception public officers could not effectively and protect
35
Warrant Exception Exigent circumstances: Preserving Evidence from Destruction
Allows officers to search/ seize w/o a warrant When 1. officers have probable cause to believe items subject to seizure are in a particular place; and 2. that waiting for a warrant would put the evidence at serious risk of destruction Common scenarios: - Suspect about to flush drugs (including “hearing people shuffling around” after police knock - Burn documents - Tamer w electronic devices - DRUNK DRIVING
36
Warrant Exception Exigent circumstances: Preserving Evidence from Destruction — Drunk Driving
Warrantless blood test - If just a normal DUI and the guy refuses consent to blood test, can’t take blood w/o a warrant (McNeally) - Can’t get around this by saying (or a law that says) if you don’t consent we will prosecute you for your refusal (Birchfield) - If you get in a wreck or something, or has to be taken to the hospital (Schmerber), or dude is passed out in his car (Mitchell) it’s fine to ask to do a blood draw - Also if DD makes it home and and is asleep you can’t blood draw (Welsh) Warrantless breath teset - For sure fine. Less intrusive – impact on privacy is slight (not like sticking a needle in you) and the need is great. (Birchfield)
37
Warrant Exceptions Boarders / Ports of Entry
Rule: searches made at the border are reasonable simply by virtue of the fact they occur at the border. Don’t even need reasonable suspicion. - Don’t want your gas tank searched? Don’t come. we treat the mail and international airports the same way FIXED v. ROVING 1. Fixed checkpoint near the border - You can stop people randomly. And even stop them worse than randomly based on race. ROVING - if it’s a roving checkpoint, then police need reasonable suspicion. (“they looked mexican” is not reasonable suspicion)
38
Checkpoints Suspicionless Drunk Driving Checkpoints
Permissible. Court compares it to border stops. The problem is incredibly large, the intrusion is small, and this would immediately improve public safety by immediately removing the danger.
39
Checkpoints Suspicionless Narcotics or General Crime Checkpoints
NOT allowed. Purpose of suspicionless checkpoints serves the purposes of border safety or ensuring roadway safety. Narcotics checkpoint doesn’t ensure roadway safety.
40
Warrant Exceptions Suspicionless Suspect Flyer checkpoint
If for a very specific purpose like handing out flyers to people near the homicide location = permissible. Very limited imposition. Not even trying too catch the people they were pulling over.
41
Warrant Exceptions Protective Sweeps
Potective Sweep = quick and limited search of premises incident to an arrest and conducted to protect the safety of officers or others. Narrowly confined to a cursory visual inspection of those places in which a person might be hiding. Scope - NOT a full search of the premises, but may extend only to a cursory inspection of those spaces where a person may be found. The sweep lasts no longer than necessary to dispel the reasonable suspicion of danger.
42
Warrant Exception Protective Sweep v. SILA
(1) the physical scope of a protective sweep will often extend beyond the area in which a SILA is permissible, (2) because sweeps are permitted only to protect against dangers to those present during the arrest, police may search only areas in which an officer may reasonably suspect a person could be found, and (3) the searches must be “cursory inspections” of those spaces. Ex: arrest guy upstairs. SILA search basement looking for evidence = no. Too far away. Protective sweep of basement = cool.
43
Warrant Exception Public School Students body & belongings search
Reasonable suspicion required - search must be justified for reasonable grounds for suspecting the search will turn up evidence the student had or is violating EITHER the law or school rules Scope of search justified - must be reasonably related to the objectives of the search and not excessively intrusive in light of the age and sex of the student. what was the reasonable suspicion that justified it? was it the advil dealer or was it the meth dealer? Balance the annoying mess of the search with the importance of the evidence.
44
Warrant exceptions Student drug tests
Suspicionless IF optional You can’t drug test everyone at a public school (or even a random sample)… but you can pretty much drug test any group of students that’s opting into something. originally said you can drug test athletes because they are more likely to use drugs than normal population, higher health risks due to physical activity, leaders at school, and optional to be on team… BUT did away with this reasoning upholding drug tests for any extracurricular activities (DECA, band, debate, quiz bowl, etc.). Only rationale seems to be “don’t like it? Don’t join.” Lower courts have even expanded this reasoning to requiring drug tests for parking passes or dance admission.
45
Warrant exception Public employee search
Reasonable suspicion Supervisors of public employees have a duty to monitor the work of subordinates for the public interest. A government employer’s warrantless search is reasonable if it is: 1. justified at its inception 2. the measures adopted are reasonably related to the objectives and not excessively intrusive
46
Warrant exception Drug testing public employees
Can’t randomly drug test any employee. Court has been reasonably open to explanations for why certain categories of employees should be subject to sucipisionless drug testing
47
Warrant Exception Drug testing public hospital patients?
Not allowed if you call the cops on the positive tests lol
48
Warrant exception Persons in jail
Obviously can search the shit out of someone locked up in the interests of safety and order for both other inmates and correctional officers. - Don’t have to be “best practices” or least invasive search - Florence v. Board of Freeholders (SCOTUS upheld as reasonable the ole “lift your balls, bend over, and cough gotta check yo booty hole” test) Also you don’t get less search for less serious crimes
49
Warrant Exception Persons on probation and parole
Search Condition = Courts review reasonableness of search if there is a search condition Probation [reasonable suspicion] - A probationer’s home may be searched if there is reasonable suspicion of criminal activity. (United States v. Knights; Griffin v. Wisconsin) Parole [suspcionless] - The suspicionless search of a parolee does not violate the Fourth Amendment. (Samson v. California)
50
Warrant exceptions inventory search of arrested persons
Suspicionless + preexisting policy - only real rule is that it can’t be a pretext. All you need is a preexisting policy that’s fair to everyone. Policy can even be “we search every car”
51
Warrant exception Administrative searches
Gov can get a warrant for fire code or housing code issues as long as they have a good faith reason to believe this neighborhood is likely to have some violations. Dangerously close to a general warrant (“search for violations of housing code in this neighborhood”) (Camera)
52
Warrant exception DNA test of arrested persons
rule = if you get arrested, the police can make you do a cheek swab DNA test
53
What is a seizure?
A person has been seized within the meaning of the Fourth Amendment only if, in view of the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave. Translation: Seizure = a reasonable person would have believed that he was not free to leave.
54
Examples of circumstances that might indicate seizure, even where the person didn’t try to leave
1. threatening presence of several officers 2. display of a weapon by an officer 3. some physical touching of the person of the citizen or the use of language or tone of voice indicating that compliance might be compelled 4. they took my luggage / keys (can effectively restrain someone)
55
Seizure “Stop in the name of the law” compliance and flight
Compliance = seizure No compliance (such as flight) = no seizure until tackled or otherwise submits
56
When are arrests reasonable seizures?
When police have a reasonable belief of guilt, they can arrest w/o a warrant. - presumptively lawful if you have probable cause to believe that he committed an offense - EVEN if it’s a really minor offense. Still constitutional. Just dumb. - EVEN IF the crime is not arrestable under state law. (state law restrictions do not alter 4A protections
57
When are stop & frisks reasonable? Reasonable stop
When a reasonable officer considering the circumstances and reasonable inferences has reasonable suspicion that the officer’s safety or the safety of other was in danger. Stop can last as long as reasonably needed to effectuate the purpose of the stop. - the mere passing of 20 minutes is not enough.
58
Terry stops Reasonable stops & dog sniffs
Reasonable diligence. If an officer can complete the purpose of the stop expeditiously, then that is the amount of time reasonably required. A stop prolonged beyond that point is unlawful. Critical question: whether the doc sniff prolongs or adds time to the stop.
59
Terry stop / stop and frisk What is a reasonable frisk
If reasonable stop then officers are allowed to conduct a quick search, confined in scope to an intrusion reasonably designed to discover guns, knives, clubs, or other hidden instruments for the assault of a police officer. Outer closthing pat down. The sole justification of the search in the present situation is the protection of the police officer and others nearby NOT a search for evidence. Only dangerous items (guns, knifes, clubs, etc.)
60
Reasonable suspicion Description and test
Described: more than a hunch, but less than probable cause. Need some objective basis. But hunch + able to write down specific things that gave you that hunch = probably enough Test: look to the totality of the circumstances and see if there is a particular lived and objective basis for suspecting legal wrongdoing. This process allows officers to draw on their own experiences and specialized training to make these inferences. Pretty low bar. Kids with high knees looking like they were told not to be suspicious in a van taking an odd route = passes
61
Reasonable suspicion Flight
Flight from police + literally anything that makes it a little more suspicious = reasonable suspicion - Flight + in a “high crime area” counts
62
Reasonable suspicion Common criminal characteristics
There are behaviors and characteristics that officers have come to recognize as being common in certain criminal trades. Observation of those characteristics can justify reasonable suspicion. This is different than profiling.
63
Reasonable suspicion & anonymous tips
Anonymous tip + more police work (i.e. they see things predicted in the tip occur) = reasonable suspicion Anonymous tip + person is where they said they would be = . . . ??? - Florida v. JL says this is not enough. Too easy to make up / prank - Navarrete = this is enough BT: idk how to square these cases. Probably better if it involves a little bit of police work. Better if it’s a tip about the future.
