Some things the GGWAG theory doesn't cover:
The Good Guy has to figure out who is the Bad Guy.
The other Good Guys with guns have to figure out who isn't the bad guy. (And hopefully not shoot the other armed people who are "just trying to help out.")
The unarmed people have to figure out who is a GGWAG and not try to stop them by a blow to the back of the head with a chair.
The Good Guy has to decide that a person is in fact guilty of a crime and deserves to get the death penalty for that crime. GG has to do this without examining evidence or talking to witnesses. He needs to become judge, jury and executioner, and violate the shooters Constitutional right to due process under the law.
Other than that, no problem.
