Worse - how about when they make mistakes, ie person is not prohibited, residence occupied by new resident, suspect disarmed themselves years ago.
It's one thing if they are politely knocking on doors or catching people outside the home to begin serving a warrant, a whole different thing if they go kicking in doors using a warrant whipped up from half baked or stale ingredients.. then who pays when an innocent person doesn't realize they are the cops and opens fire or the cops shoot someones dog, injure innocent people etc
