Federal crime refers to crime that violates federal law. Federal crimes are prosecuted in federal courts. The Federal Bureau of Investigation (FBI) has the ability to investigate federal crimes, and these investigations often lead to trials in federal courts.
Examples of federal crimes include kidnapping, tax evasion, destroying public mailboxes, and immigration offenses.
Jurors for federal court cases are still selected from peers in the area where the federal court is. The main difference between a federal court and a state court is that state courts prosecute infractions against state laws, and federal courts prosecute infractions against federal laws.
It is the obligation of citizens in the country to adhere to both state and federal laws, or else they can be prosecuted. Punishments for violating federal laws can often be severe.
