this makes sense.The author accurately describes that rifle cartridges are more powerful than handguns. That is a "no duh" assertion. There is no question that rifles are more powerful. But the author of that article also asserts that "AR-15 or other high-velocity weapons, especially when outfitted with a high-capacity magazine, have no place in a civilian’s gun cabinet." That is a demonstrably false claim. Banning anything as or more powerful than the .223 Remington would ban probably something like 90% of all rifle cartridges in existence, including those that are most suitable to hunting. It would outlaw the rifles that the vast majority of hunters in this country use for game such as antelope, wild sheep, deer, elk, moose, and bear.
the practical issue, then, becomes not that a person can fire one of these rounds. it's that they can fire these rounds in quick succession. so back to the bigger issue - where we need to completely ban semi automatic rifles for consumer sale.
wouldn't mind a compromise, though. a ban is the simplest solution, but if you have something else in mind that reliably prevents a school shooter from firing more than one round every 10 seconds or so, that would cover it.
and yes - i am applying this to all types of semi automatics. not just rifles.
