Yes
What are examples of involuntary acts?
Do involuntary acts satisfy the actus reus?

Are acts performed under duress considered voluntary acts?

mens rea
D’s state of mind during a crime. D must have a “culpable state of mind” to be convicted of a crime.

No, it is sufficient that the act was performed
What are the 4 main categories of strict liability crimes?
Remember MARS: “life is strict on Mars”
What intent do specific intent crimes require?
Subjective intent to cause a specific outcome
What are some common specific intent crimes?
Remember acronym “BRAM-ACTS”
What do general intent crimes require?
D intended to commit the criminal act
⚠️ Note: Unlike specific intent, general intent crimes do not require subjective intent to bring about a certain result; only to commit the act itself

What are the 4 categories of mens rea under common law?
What are the 4 categories of mens rea under the MPC?
When does D act “purposely” for the purposes of MPC mens rea?
With the conscious objective to produce the result or engage in the particular behavior
⭐️ Subjective standard
When does D act “knowingly” for the purposes of MPC mens rea?
When he knows that a course of action will almost certainly produce a specific result
⭐️ Subjective standard
Differentiate between purposely and knowingly
Purposely: D desires to produce a specific result
Knowingly: D is aware that a specific result is almost certain to occur
Ex. If Max shoots Brianne at close range and kills her, he has acted “purposely”
However, if Max means to kill Brianne, and he places a bomb in the car that he knows is carrying both Brianne and Mat, it is unlikely he could be charged with “purposely” killing Mat, but will likely be charged with “knowingly” killing Mat
When does D act “recklessly” for the purposes of MPC mens rea?
When D “consciously disregards a substantial and unjustifiable risk”
⚠️ Note: Majority uses a subjective standard, minority uses an objective standard
When does D act “negligently” for the purposes of MPC mens rea?
When, regardless of whether D was actually aware of the risk, D should have been aware of a substantial and unjustifiable risk
Differentiate between criminal negligence & civil negligence
Criminal negligence: gross deviation from the normal standard of care
Civil negligence: deviation from the normal standard of care
