The plural of anecdote is not data.
Every single time this topic comes up here there are always one off incidents of how violent the police are, or are not. These one off's really aren't useful either way.
Also another reason why police arrive here with guns drawn when they've been called to some kind of incident/argument/disturbance is there is a much higher chance that someone here has a gun and could do them harm. I'm not sure why everyone glosses over that fact when the USA has 300 million guns vs. some place like London.
