Outlaw. In old British law, an outlaw was a person put outside the protection of the law because of treason or felony, or for other reasons. An outlawed person could be killed on sight. Parliament abolished outlawry in 1879. In the United States outlawry has not been in effect since the Revolutionary War.
In common speech an outlaw is a lawless person, or bandit, who is a fugitive from justice. Widely known outlaws include Billy the Kid, Jesse James, Rob Roy, Robin Hood, and Dick Turpin.
