So, basically, we have data and evidence that high capacity magazines can reduce shootings or the deadliness of shootings? Not quite certain on the conclusion but it would help.
Seems like I could support this. I've seen the counters to this point showing that it is retarded as hell to put a regulation in place against high capacity magazines because you can either buy one illegally to do your illegal thing (duh) or simply swap out your magazine extremely quickly.
