Everyone that knows me knows to call before showing up. If you're at my door and you didn't call; I assume the worse, either you're a salesman (and deserving of death) or a cop. Luckily, I'm not a criminal so if it's a cop, he's there for something minor like selling me police man's ball tickets.
These no knock warrants and plain clothes warrants are deadly and need to be stopped. The WOD is not worth an innocent civilian's or cop's life.
Girl scouts sell cookies door-to-door, without calling first...
