Found this video. Really well done with good points. By a Sheriff in Indiana. Maybe you've seen it but interesting if you haven't. Maybe we should send this to Crynan. Wasn't it him that said it takes twenty seconds to change a magazine?

A somewhat edited version was posted before and IMHO it loses a certain amount of it's credibility when you see that the rate of fire is faster in the instances when attempting to prove the thesis. Listen to it without the video and you'll see what I mean. I believe that is why it's not used more widely as an example by the pro gun sites. Still it does hold some good basic information.
