Take it a step further and see if you can find statistics on how long it takes to commit a rape, a murder, our a basic robbery or mugging.
Now, like I pointed out in another thread (our heck it could even be this one, I don't read the entire thread every time, just the updates.)
take your favorite carry piece and aim it at a target. It could be a home intruder if you have one on hand, but a paper plate will do in a pinch. With one hand dial 911, and ask for the police, and with the other hand open fire.
Which reaches it's destination first? The bullets or the cops?
