Defense can have a variety of meanings:
1. It is the facts, legal theories, arguments and evidence presented in
opposition to a criminal charge or civil claim.
2. It is a legal justification for conduct that would otherwise be wrongful
or illegal. For example, when a person kills someone to protect himself
or another person, at his murder trial, he would claim self-defense.
3. It is the team consisting of the defendant and his or her attorneys.
