Dirty cops

I was on a internet forum(I won't say which because they don't deserve it) and the subject of cops and "throwaway guns" came up. Some people stated how they could understand why a cop would carry one. Are these jerks for real? I'm sorry but if you're a cop and you carry a throwaway gun, you're a worthless dirty cop. Many cops these days have some kind of an ego trip and think they're somehow more important than the average Joe.
