Q

Can a defendant use deadly force to protect a criminal or initial aggressor who had no right to use self-defense against their attacker?

A

Majority, a defendant may claim defense of others if the victim reasonable appears to have the right to use deadly force, even if the other does not actually have that right (mistake allowed)

Minority, a defendant can use no more force than that person they are defending (steps into the shoes, no mistake allowed)

45
Q

When is the excuse of intoxication going to excuse one from criminal liability?

A

Voluntary intoxication can negate specific intent crimes but only if the defendant is so intoxicated he cannot perform the specific intent required for the crime. It may also preclude a finding of deliberation if the defendant is charged with First Degree Murder.

46
Q

Is voluntary intoxication an excuse to all crimes?

A

No. It is not an excuse to general intent crimes, no intent crimes (strict liability), or malice. It is only an excuse to specific intent crimes if the D was so drunk he could not form the requisite specific intent.

A

When the defendant involuntarily (forced to consume) or unknowingly (voluntarily consumed without knowledge substance was intoxicant) becomes intoxicated.

A

Defendant must have been actively provoked losing self-control and did not cool off before killing the victim.

Inflicting a staggering blow

Catching a spouse in an act of adultery with the victim

57
Q
