i thought it was relevant to a couple of pro and anti gun control issues, though im sure it was not the purpose of the demo.
1) it is a screaming testimony for Florida and (other states) repealing it's law prohibiting ccw in businesses that serve alcohol, cause if someone can conceal an AR and that many 30rd mags on his way into a location with no metal detectors, it is more logical for ccw people to be able to return fire. and for the record, I vehemently, categorically, disagree with such laws in the first place - Wayne Lapierre and his likeminded Bernophile Republican nominee are dead wrong on this one.
2) it also illustrates the absurdity-as if the absurdity wasn't obvious already-of laws that limit magazines capacities; because whether this guy would be loaded up with 30, 10, 7, or 5 round magazines, he could still kill a boat load of people.
and I say that being fully aware and certain that if Democrats banned every firearm but single shot derringers, and someone walked into preschool and killed a single kid with that weapon, they would promptly call for the prohibition of SS derringers... and of course, we ALL know that THAT is the intended end result of incremental gun bans.
