Criminal Law in the U.S.

Criminal law in the U. S. is codified, or written down, and accessible to all.

Criminal law is contained in several sources:---U. S. and state constitutions---Statute (laws) passed by Congress and state legislatures; ordinances

---Regulations created by governmental agencies

---Case law (court decisions)

Page 3: Introduction to Criminal Justice

Constitutional Law

Contained in U. S. constitution and constitutions of the states

U. S. Constitution is supreme law of the land

Each state constitution is the supreme law in that state

Conflict between federal and state law, federal law prevails

Page 4: Introduction to Criminal Justice

Statutory Law

Congress - Federal laws - applies to all states

State legislatures - State laws – within the state’s borders

Local authorities - ordinances – apply only to the jurisdictions where it was enacted

Page 5: Introduction to Criminal Justice

Administrative Law

The rules, orders, decisions of regulatory agencies.

Department of Transportation and driving privileges.

Food and Drug Administration

Page 6: Introduction to Criminal Justice

Case Law

The rules of law announced in court decisions

The whole body of laws and decisions that have gone before---precedent

Judges interpret constitutional provisions

Miranda v. Arizona Mapp v. Ohio

Page 7: Introduction to Criminal Justice

Purposes of Criminal Law

Punish and protect (legal function) Maintain social order Maintain and teach (social function) Teach society changing needs of

morality Teach society’s boundaries and

expectations Express public morality—values and

norms

Page 8: Introduction to Criminal Justice

Law Terminology

Page 9: Introduction to Criminal Justice

Actus reus

The guilty act The actual physical act The voluntary commission of a

crime took place Someone had to do something Thinking about something wrong is

not a physical act Must be a prohibited act

Page 10: Introduction to Criminal Justice

Mens rea

The guilty mind: Elements of purpose, knowledge, negligence, recklessness Purposefully committed a criminal act Knows of the illegality of the act Criminal negligence is the deviation of

what a reasonable person would have done

Criminal reckless is “consciously disregarding a substantial and unjustifiable risk

Page 11: Introduction to Criminal Justice

Mens Rea Example

For theft, the required mental state is knowing that the property belongs to another and the desire to deprive the owner of it(The two most used words in the Code of Iowa are knowingly and willingly, followed by intentionally.)

Page 12: Introduction to Criminal Justice

Criminal Liability

The criminal act (actus reus) and guilty mind (mens rea) must be concurrent (occur at the same time).

The criminal act must have caused the harm suffered.

Proximate cause---”but for” the actions of the defendant, the harm would not have occurred.

Liability differences lead to different penalties

Page 13: Introduction to Criminal Justice

Causation

Criminal law requires that the criminal act cause the harm suffered

Historically, the courts have held that a victim’s death must occur within one year and a day before the act to be considered a criminal act Michigan Supreme Court allowed a

murder charge to be filed when the victim died four years later

Page 14: Introduction to Criminal Justice

Strict Liability

For certain crimes criminal law holds the defendant to be guilty even if intent to commit the offense is lacking.

Example - Traffic violations - I need not know what the speed limit was; or

---that I was not paying any attention and have no idea how fast I was going; or,

---that my speedometer was off.

Page 15: Introduction to Criminal Justice

Accomplice Liability

Under certain circumstances I can be found guilty of a crime even though I did not actually commit the crime.

If I aid and abet in the crime but did not pull the trigger I can still be charged with murder.

“Dual intent” is required--- ---To aid person convicted of crime

---Knew such aid likely to lead to crime

Page 16: Introduction to Criminal Justice

Attendant Circumstances

Adds to the degree of the crime - If an offender commits sexual abuse and had used a firearm to get my victim to submit

The use of a weapon in an assault The amount of money stolen Present tendencies are to impose harsher

mentalities if the offense is motivated by race, ethnicity, religion, gender, sexual orientation (hate crimes)

Page 17: Introduction to Criminal Justice

Harm

Harm to a person or property The degree of the harm done – stole

$5000.00 rather than $500.00 Hit a person in the back of their head

with a tire iron--He/she dies vs.--He/she is knocked unconscious

Page 18: Introduction to Criminal Justice

Inchoate Offenses

Conduct deemed criminal without actual harm being done, provided that the harm that would have occurred is one the law tries to prevent.

Solicitation to commit a crime Attempts The conspiracy to commit a crime

Sale of drugs Other crimes

Page 19: Introduction to Criminal Justice

Types of Defenses

A defense consists of evidence and arguments offered by the defendant to show why he/she should not be held liable for a criminal charge

Our system generally recognizes four broad categories of defense Alibi Justifications Excuses Procedural defenses

Page 20: Introduction to Criminal Justice

Types of Defenses

Alibi – different from the other defenses as it is based on the premise that the defendant is truly innocent An alibi is supported by witnesses and

documentation – hotel receipts, eyewitness identification

Page 21: Introduction to Criminal Justice

Types of Defense

Justification – claim of moral high ground; a choice between the “lesser of two evils” Example: a firefighter who sets a

“control” fire to create a firebreak to save the town; The setting of the fire is arson, but the intent was to save the town.

Self-defense; defense of others; defense of home and property, necessity, consent, and resisting unlawful arrest

Page 22: Introduction to Criminal Justice

Justifiable Use of ForceSelf Defense You must use only the force necessary to

protect yourself, your dwelling, your property, or to prevent a crime.

Deadly force can only be used to protect you from imminent death or bodily harm.

You must not have provoked the attack, and there must be no alternative.

You must have a reasonable belief that death or bodily harm will otherwise occur.

Page 23: Introduction to Criminal Justice

Types of Defenses

Excuses – the person who engaged in the unlawful behavior was, at the time, not legally responsible for his/her actions

Recognized excuses include: Duress - Involuntary

Intoxication Age - Unconsciousness Mistake - Provocation Insanity -Diminished capacity Mental incompetence Necessity

Page 24: Introduction to Criminal Justice

Duress

The wrongful threat of one person induces another person to perform an act that she or he would otherwise not perform. Girlfriend helps boyfriend commit a

robbery as he threatens to kill her kids The threat must be immediate and

inescapable

Page 25: Introduction to Criminal Justice

Duress

The threat must be of serious bodily harm or death

The defendant must have become involved in the situation through no fault of his or her own

Page 26: Introduction to Criminal Justice

Age (infancy) as a Defense Under a certain statutory definition

you do not meet the maturity level to make the decisions necessary to commit a crime.

Page 27: Introduction to Criminal Justice

Mistake

Ignorance of the law is not a valid excuse

Mistake of fact – getting into a car that looks just like yours and putting the key in the ignition and it works and you drive away is not a crime.

Page 28: Introduction to Criminal Justice

Insanity Case Law

Insanity – a legal definition not a medical definition M ’Naghten Rule – the inability to

distinguish right and wrong must be the result of some mental defect or disability

Irresistible Impulse – Defendant knew it was wrong but could not stop doing it because of some irresistible impulse Schizophrenia

Page 29: Introduction to Criminal Justice

Insanity Case Law

Durham Rule--a person is not criminally responsible for his /her behavior if the person’s illegal actions were the result of some mental disease or defect

Substantial capacity rule—lacks capacity to appreciate the wrong/or to conform to the law

Page 30: Introduction to Criminal Justice

“Guilty but mentally ill”

Jury may decide---defendant mentally ill, but not insane

Responsible for his acts Defendants spend early years in

mental hospital; to prison at some point

Page 31: Introduction to Criminal Justice

Insanity Defenses

Temporary Insanity – Insane only at the time of the criminal act

Diminished Capacity – Used not to be declared not guilty, but a lesser sentence; from Murder 1st degree to Murder 2nd

Mental Incompetence – Incapable of understanding the charges against them, consulting with attorney, or in aiding in their own defense

Page 32: Introduction to Criminal Justice

Intoxication

Involuntary intoxication is when a person is physically forced to ingest a substance.

Involuntary can also be a reaction to a legal prescription drug which caused psychotic episodes as a side effect.

Voluntary intoxication is becoming intoxicated on your own. (Claim that there is no mens rea)

12 states have eliminated it as a defense.

Page 33: Introduction to Criminal Justice

Necessity (Lesser evils)

A defense against criminal liability in which the defendant asserts that the circumstances required her or him to commit an illegal act.

Justifiable if harm avoided by your illegal conduct was greater than that sought to be prevented in the offense charged

Violating a restraining order to save your former spouse from drowning would avoid the greater evil

Page 34: Introduction to Criminal Justice

Procedural Defenses

Procedural Defenses – claim the defendant in some manner was discriminated against in the justice process, or some important aspect of official procedure was not properly followed entrapment Double jeopardy police fraud selective prosecution denial of speedy trial Prosecutorial misconduct

Page 35: Introduction to Criminal Justice

Entrapment

When police deceives defendant into wrongdoing

Defendant would not otherwise have committed crime

Police cannot “plant the idea” in defendant

Defense used in some undercover drug cases

Page 36: Introduction to Criminal Justice

Legal Safeguards

Substantive criminal law---defines specific acts government will punish

Procedural criminal law---defines procedures which must be followed in adjudicating defendants

Page 37: Introduction to Criminal Justice

Bill of Rights

First ten amendments to U. S. Constitution, adopted in 1791

U. S. Supreme Court has interpreted all of them

Serve as a safeguard for accused criminal defendants

Procedural safeguards come primarily from 4th, 5th, 6th and 8th amendments

Page 38: Introduction to Criminal Justice

Fourth Amendment

Protects from unreasonable searches and seizures

No warrants for a search or arrest can be issued without probable cause

Probable cause is reasonable grounds to believe the existence of facts warranting certain actions, such as a search or arrest.

Page 39: Introduction to Criminal Justice

Fifth Amendment

No one may be deprived of “life, liberty or property” without due process of law.

No double jeopardy No person can be forced to be a

witness against himself (“taking the fifth”)

Page 40: Introduction to Criminal Justice

Sixth Amendment

Guarantees a speedy trial, trial by jury, a public trial

Right to confront witnesses, right to a lawyer

Page 41: Introduction to Criminal Justice

Eighth Amendment

Protects against excessive bail and fines

Protects against cruel and unusual punishment (Does not include the death penalty)

Page 42: Introduction to Criminal Justice

Due Process of Law — 14th Amendment Government cannot act arbitrarily or

unfairly Must stay within the boundaries of

reason and the law Procedural due process—law must be

carried out fairly and orderly Substantive due process—laws

themselves must be reasonable Supreme court has big role in

interpreting these requirements

Page 43: Introduction to Criminal Justice

Hate Crimes

Offense motivated by hate or bias Can involve race, ethnicity, religion,

gender, sexual orientation, disability Many states have passed laws enhancing

penalties for other crimes involving hate Some of hate laws have been challenged

as violation of constitutional rights Say individuals have right to beliefs Tends to protect certain victims more than

others
