Mens Rea:
The Criminal State of Mind
To be found guilty of a crime, the
prosecution must prove that there was a physical action, actus reus, and a state of mind to commit a crime, known as mens rea. Mens rea is concerned
with what the defendant was thinking at the time he committed the actus reus. Different crimes have different mens rea requirements.
The purpose of this presentation is to
provide an overview of mens rea. First, the presentation will introduce
the different categories of mens rea. Next, the presentation will analyze each
of these categories, provide the key components to each, and will provide
examples of crimes that are classified under these mental states.
Overview of Mental States
Mens
rea is divided into three
categories: general intent, specific
intent, recklessness/criminal negligence. Additionally, there is a class of
crimes for which no mens rea element is required. These are
called strict liability crimes. Strict liability crimes are crimes for which
liability is imposed without consideration of the defendant’s knowledge or
intentions.[1]
General Intent
General intent crimes require that the
defendant had the intention to commit an illegal act. All that is needed for a
conviction is an intent to commit the act that constitutes the crime. General
intent exists when the illegal act may reasonably be expected to follow from an
offender’s voluntary act even without any specific intent by the offender.
To prove general intent, the prosecution
must demonstrate that the defendant acted intentionally in the sense that he
was aware of what he was doing. For general intent crimes, the very doing of
acts that have been declared criminal shows the criminal intent necessary to
sustain a conviction. For example, a defendant can be convicted for the illegal
skinning of an alligator if he is merely in possession of an alligator that was
not appropriately skinned. This is because a jury may infer the required
general intent merely from the doing of the act. Some examples of general
intent crimes are the following:
·
Rape
·
Battery
·
False
imprisonment
·
Kidnapping
Specific Intent
Specific intent designates a special
mental element that is above and beyond any mental state required with respect
to the actus reus of the crime.[2]
Specific intent is a term used to describe a state of mind that exists where a
defendant objectively desired a specific result to follow his act. The
prosecution must prove that the defendant acted with the intent to achieve a
specific goal, as well as the intent to commit the illegal acts. Specific
intent cannot be inferred from the commission of the act and specific proof is
required to demonstrate that this element is satisfied.
Conspiracy is an example of a crime
requiring the mens rea to be specific
intent. The general federal conspiracy statute provides, ‘[i]f two or more
persons conspire . . . to commit any offense against the United States . . .
each shall be fined not more than $10,000 or imprisoned not more than five
years, or both.’ 18 U.S.C. § 371. ‘[T]he specific intent required for the crime
of conspiracy is in fact the intent to advance or further the unlawful object
of the conspiracy.’
Other examples of specific intent crimes
are:
·
Attempt
·
Assault
·
First
degree premeditated murder
·
Burglary
·
False
pretenses
Criminal Negligence and
Recklessness
There are also crimes that require
neither specific nor general intent. A prosecutor can secure a conviction by
demonstrating that the defendant acted recklessly or negligently. Both
recklessness and criminal negligence may exist when the defendant acted with a
gross lack of care without paying attention to the unjustifiable risk that the
circumstances exist or the result will occur. Recklessness is a higher level of
guilt than criminal negligence. Both negligence standards and the possible
criminal charges stemming from criminal negligence vary state to state.
Even though there are variations, the defendant’s
mental state must be of such a nature and to such a risky degree that the
failure to perceive the risks of his actions constitutes a gross deviation from
the standard of care that an ordinary person would exercise. Unlike general or
specific criminal intent, criminal negligence is negative, meaning it does not
require an affirmative act by the defendant.
An example of a conviction based on a
showing of recklessness occurred in a case involving drag racing.[3]
The defendant was convicted of negligent homicide as the result of illegal drag
racing, where speeds were at least forty miles per hour over the speed limit.
After two vehicles engaged in such reckless driving, there was a crash and a fatality.
The prosecution successfully proved that the defendant’s mental state was
reckless. In convicting the defendant, the court reasoned that driving at those
speeds while drag racing “exhibited such disregard for the interest of others
as to amount to a gross deviation below the standard of care expected of a
reasonably careful man.”
Strict Liability
There is another class of crimes referred
to as strict liability crimes. Strict liability crimes, also known as public
welfare offenses, are crimes that do not require mens rea. The defendant could be found guilty merely because he
committed the act. Some examples of crimes that fall into the strict liability
category are:
·
Statutory
rape
·
Selling
alcohol to minors
·
Bigamy
Statutory rape is a strict liability
crime because even if the offender believed their partner was of consenting age, he is still guilty of committing the crime so long as the victim is under a
certain age. These laws, even though very severe, are intended to protect
certain classes of individuals from certain kinds of conduct.[4]
Determining whether a crime is a strict liability crime depends on the state
legislature’s intention.
