Did Trump Just Legalize Murder? When asked by reporters who should be held responsible for Khashoggi's death, Trump said "maybe the world should be held accountable because the world is a vicious place."

CAN ANYONE USE TRUMP'S EXCUSE? For Example: What if Someone committed any Crime and Blamed the World... Would THAT hold up as a Defense at a TRIAL? Would Lee Harvey Oswald have been Given a "Mulligan?"

[A mulligan is a second chance to perform an action, usually after the first chance went wrong through bad luck or a blunder. Its best-known meaning is in golf, whereby a player is informally allowed to replay a stroke, even though this is against the formal rules of golf.]
