Criminal cases involve legal proceedings where the government accuses an individual or entity of committing a crime. Unlike civil cases, which deal with private disputes between parties, criminal cases are initiated by the government to punish individuals for violating laws that are deemed to be offenses against the public or the state. Here are key aspects of criminal cases:

1. Types of Crimes:
   1. Felonies: Serious offenses such as murder, robbery, and burglary, often punishable by imprisonment for more than a year.
   2. Misdemeanors: Less severe offenses like petty theft, simple assault, or minor drug possession, usually punishable by less than a year of imprisonment.
2. Initiation of Criminal Cases:
   1. Investigation: The police or law enforcement agencies conduct an investigation into alleged criminal activity.
   2. Arrest: If there is sufficient evidence, the suspect may be arrested.
   3. Charging Decision: Prosecutors decide whether to file formal charges based on the evidence provided by law enforcement.
3. Criminal Complaint and Indictment:
   1. Complaint: A formal charging document filed by the prosecutor, outlining the charges against the defendant.
   2. Indictment: In some cases, especially for serious offenses, the prosecutor may present evidence to a grand jury, which decides whether to issue an indictment.
4. Arraignment:
   1. The defendant is brought before the court, informed of the charges, and asked to enter a plea (guilty, not guilty, or no contest).

   2. Opening Statements: In most cases, a jury is selected to hear the evidence and render a verdict.
