Extradition is the process of one nation or state surrendering a suspected or convicted criminal. Extradition laws allow for any criminal who has crossed state or country borders to be returned to the location of the crime for an arrest or a trial. Extradition laws are both nationally and internationally recognized, respected, and followed.
In some instances, justice can be a somewhat subjective term. This is to say that sometimes members of a concerned public will view the effects of laws and judicial decisions, and decide that justice was not done by them. In this regard, rather than adhering to a strict interpretation of the legal code or waiting for new pieces of legislation to be passed, these individuals will go on the offensive, so to speak, and take matters into their own hands.
