Treason

Treason is doing something the government doesn't like. It originated with doing something the King didn't like, such as failing to take your hat off in his presence. Unfortunately, treason is one of the aspects of the feudal system that modern governments have decided to continue."Treason" often has little to do with what's bad for the nation.My policy has always been to keep my own secrets. I don't tell you a secret and then blame you for leaking it.

Exactly. The government can construe "aid and comfort" to be virtually anything that it doesn't want you to do. Thus, treason is effectively defined as anything the government doesn't want you to do. Of course, it could be difficult to get a conviction using a questionable notion of "aid and comfort" but we're not talking about convictions, are we? We're talking about casually throwing accusations around.
