UNIT 2: Criminal Law & Juvenile JusticeChapter 11Defenses
For a conviction to occur in a criminal case, two requirements must be metThe prosecutor must establishbeyond a reasonable doubtthat the defendant committed the act in questionand that the defendant committed the act with the requiredintent
The defendant does not have to present a defenseHe or she can simply force the government (the prosecutor) to prove its caseHowever, several defenses are available to defendants in criminal casesFor example, sometimes a criminal act may be considered excusable or justifiableDefenses in this category include self-defense, defense of property, & defense of others
O.J. Simpson Case
One of the most publicized criminal cases in recent years was the murder trial of former football star O.J. Simpson, in which he claimed he wasn’t guilty in the killings of his ex-wife & her friendBy focusing the defense on improper police behavior & investigation techniques, his legal team convinced a jury there wasreasonable doubtas to his guilt
He was found not guilty on all countsIn a civil case for wrongful death brought by the surviving family members, a jury found that apreponderance of the evidencewent against SimpsonHe was found liable & ordered to pay compensatory & punitive damages to the families of the two victims
The idea behind the two different standards is that the penalty in criminal cases is much more seriouscriminal record,imprisonment, &possible death sentenceCriminal penalties involve infringement on an individual’s liberty (and possibly life) in contrast to the lesser penalty in civil cases, which is usually only monetary damages

Fill out bottom of Basic Concepts Handout
No Crime Has Been Committed
The defendant may decide to try to prove that(1) no crime was committed, or(2) there was no criminal intent because the act was simply committed by mistakeAnswers:#5 – Elements of the crime were not all present#10 – Lack of criminal intent
Defendant Did NotCommit the Crime
When there is confusion or doubt about who committed a crime, the defendant may try to prove that there has been a case of mistaken identity & that he or she was not the person responsible for the crimeToday, DNA testing can sometimes be used to prove whether or not the defendant was responsibleIn recent years, some people convicted of crimes have been able to prove their innocence because of this testingAnswers:#1 – Alibi#11 – Mistake in identity
Defendant Committed a Criminal Act,but the Act Was Excusable or Justifiable
Sometimes a criminal act may be considered excusable or justifiableThis type of defense includes (13)self-defense&defense of (3) property & (2) othersThe law allows people to usedeadlyforce when their own or someone else's life is in dangerThe law also permits people to usereasonableforce to protect themselves, their property, & others from harm
Bernhard Goetz—Self-Defense
One famous case of self-defense involved a man named Bernhard Goetz, who shot four teens in what he claimed was self-defense while riding on a New York City subway trainGoetz had been mugged & robbed of electronic equipment on a subway train a few years earlierHe feared it would happen again, especially in his neighborhood, which was frequented by drug addicts & other criminals
Therefore, Goetz applied for a license to carry a gun to protect himselfHe was denied permission but obtained a gun anywayOne day he was surrounded in a subway car by four youths who first asked him for “the time,” then “a match,” & then “five dollars to play video games”
Goetz replied, “I’ll give you each five dollars,” & pulled a .38 revolver from his pocket & shot all four youthsEvidence showed that he shot one in the back as he lay on the floorGoetz ran from the train & escaped but was later arrestedAll four youths were seriously hurt & one was permanently paralyzed
Three carried sharpened screwdrivers in their pockets at the time of the shooting that they may have used to pry open video game machines to obtain quarters
If Goetz were tried for assault, what would he have to establish to prove self-defense?
Based on the facts, do you believe this was a case of self-defense?
Should the teenagers be charged?If so, with what crime?
Should citizens be allowed to carry guns & use them in self-defense?
Was Goetz guilty of a crime?If so, what crime?If convicted, what penalties, if any, do you think he should face?
Goetz was eventually acquitted for attempted murder & assaultHe was found guilty of illegal possession of a deadly weapon & reckless endangerment, & spent time in prison
Defendant Committed a Criminal Act but Is Not Criminally Responsible for His or Her Actions
In this type of defense, the defendant acknowledges that he or she committed the act but argues that there are reasons the law should not consider the defendant criminally responsibleThe law recognizes several reasons that may excuse a defendant from criminal responsibilityThese defenses include (7) infancy, (8) intoxication, (9) insanity, (6) entrapment, (4) duress, & (12) necessity
Infancy Defense
Theidea behind the infancy defense is similarto theinsanity defense:Peopleshould not be convicted or punished if they do not know right from wrongIf a three-year old child plays with matches, starts a fire, & thehouse burns down, is it arson?What if the child were eight years old?Eleven years old?Sixteen years old?Would your answers differ if kids of the same age were fighting & one shot the other?
Defendants claim that at the time of the crime they were so drunk or high on drugs that they did not know what they were doingVoluntary intoxication is not a defense to a crimeHowever, it may be a valid defense if the crime requires proof of a specific mental state
Example:Grady is charged with assault with intent to killHe claims he was drunkIf he can prove that he was so drunk that he could not have formed theintentto kill, his intoxication might be a valid defenseGrady can still be convicted of the crime of assault, because specificintentis not required to prove that crimeHowever, if Grady had decided to kill the victim before he got drunk or if he got drunk to get up enough nerve to commit the crime, the intoxication would not be a defenseThis is because the required mental state (the intent to kill) existed before the drunkenness
Insanity Defense
The basic concept is that people who have a mental disease or disorder should not be convicted if they do not know what they are doing or if they do not know the difference between right & wrongThere is a difference between not guilty by reason of insanity (used by most states & the federal government) & not competent to stand trial that exists in some states
The accused’s mental state can be an issue in determining whetherThe defendant is competent to stand trialThe defendant was sane at the time of the criminal act, &The defendant is sane after the trialThe insanity defense applies only if the accused was insane atthe time of the crime
How & when may a state determine that person found not guilty by reason of insanity should reenter society?Who should make that decision?
