If you're a secret agent, everybody is allowed to shoot at you but nobody is allowed to hit you. You're allowed to shoot at all the bad guys with stellar aim, but when it comes to hitting the MAIN bad guy at close range, suddenly you can't hit the broad side of a barn.
The main bad guy is, on the other hand, allowed to CAPTURE you ONCE. But when he does, he isn't allowed to shoot you. He's only allowed to leave you with one of his bumbling henchmen, or another option is simply holding a gun to your temple but NEVER squeezing the trigger even as you develop a complex and risky means for escape.
