Yes, I know, that's my point. Please re-read __Rick__'s post and my rebuttal. He's the one conflating mass shootings and firefights.
The point of the video is that magazine capacity is very important for defending against armed assailants (firefight), but almost entirely irrelevant when shooting unarmed targets (mass shooting). Therefore, limiting magazine capacity only harms law-abiding firearm owners.
But the video makes some critical assumptions right? Doesn't matter what side you're on, you have to admit this video isn't really slam dunk evidence of anything. It assumes that a mass shooter is shooting as fast as he can pull the trigger. Maybe in the beginning when you're in a crowded room. But people run. They hide. Your first couple will be easy pickings. So showing showing similar times, great, only if your aim is to shoot as fast as you can.
The video doesn't deal with live targets. Don't you think the thoughts going through a killer will change if he didn't have to worry about reloading so often? When shooting a 100 round drum, don't you think he wouldn't worry about a round or two extra going in someone? So if someone's running across the room to the exit, he might put a round or two or three into him before switching to another fleeing victim. You think he'll expend a couple extra rounds when he's limited to 10? It might be a round before seeing the victim fall and then he moves onto another target. Let's not even forget this is assuming 100% accuracy.
Let's not even mention that the video has the magazines ready right next to the shooter. Do people walk into shootings like that? The VT shooter had a bag of ammunition, and while you can certainly carry some on hand, it's also likely that he needed to fumble through his bag at a certain point for more rounds. Do you really think mass shootings also have the ideal reload situation? Then the shooters also get more desperate as time goes on. It becomes a frantic search for the targets. Time starts ticking as the clock counts down til when law enforcement shows up. I'm sure SOME of it has some mental strain on the shooter.
I don't disagree that limiting magazine capacity will limit defensive capabilities. It's certainly an issue we need to look at, and I agree it's a great argument against limiting magazine capacities.
However, acting like magazine size has ZERO effects on a mass shooter is ridiculous. If you give a shooter enough time with a bolt action rifle in a room of 100 people, he can shoot all of them and kill them all. Give him a AK with a 100 round drum and he can do it much faster.
There's no "video" out there that can show you these things, but these basic psychological responses to magazine size is pretty self evident.
