Let's say you either can't or won't become a professional football player. Don't worry, you can still get away with murder! All you have to do, according to a Justice Department memo, is identify your target as a "senior operational leader" of an undesirable faction. Then you can kill him all you want, without even having to demonstrate the presence of an active plot to attack the country.
In 17 states, though, you can't execute a convicted criminal, no matter how heinous his crimes. So it's not enough to convince your target to become a raping murderer. Instead, you have to get him to associate with undesirables. Then you're home free.
