What Makes Something a Crime?

For an act to be considered a crime, it must meet certain elements that make it illegal. A criminal offense will typically include two essential elements – the criminal act (actus reus) and criminal intent (mens rea). The criminal act is the action or conduct defined in law as an offense, such as theft or assault. The criminal intent refers to the mental state of the accused when committing the act, such as purposely, knowingly, or recklessly committing a prohibited act. If either of these elements is missing, the criminal act may not have occurred in the eyes of the law.

Types of Crimes

Criminal laws categorize offenses into different types of crimes based on seriousness, with felonies considered the most serious. Common law felonies include murder, rape, arson and burglary. Other felony crimes are defined by specific state and federal statutes. Misdemeanors, like petty theft and drunk driving, are considered less serious and typically incur lighter punishments. Infractions or violations cover minor offenses like traffic tickets.

Key Criminal Defenses

When prosecuting a crime, the state must prove beyond a reasonable doubt that the defendant committed the criminal act. Defendants have several legal defense strategies available to avoid conviction, such as:

  • Alibi: Defendant was elsewhere at the time and could not have committed the crime.
  • Self-defense: Admitting to the act, but arguing it was necessary for protection against harm.
  • Insanity: Defendant lacked sound mental capacity to understand their actions were criminal.
  • Consent: Admitting to the act but arguing the other party consented.

Overview of Criminal Procedure

The criminal procedure process has several stages including:

  • Investigation: Police gather evidence and identify suspect(s).
  • Arrest and Charging: Suspect is arrested; charges filed based on probable cause.
  • Bail Hearing: Court determines if defendant can be released from custody pre-trial.
  • Plea Bargaining: Defendant may plead guilty in exchange for reduced sentencing.
  • Trial: Prosecution must prove beyond reasonable doubt defendant committed the crime.
  • Sentencing: If found guilty, defendant receives punishment such as jail time.
  • Appeal: Convicted defendant can appeal to higher court to overturn decision.

Criminal law provides the structure for how our justice system prosecutes crimes and punishes offenders. Understanding its key foundations enables citizens to better navigate and participate in the criminal procedure process. With legal counsel, individuals can also assert their rights and best interests during any encounters with criminal law.
