Yeah, that line caught me, too; whatta crock.
If you factor in all the kids out there playing paintball, hunting with their Dads/Grandfathers/Uncles, logging time with FPS video/computer games (that teach THINKING and PLANNING -- hello? STRATEGY? -- not just visceral reaction), there's a REALLY good chance that the 21 or 22 year old student knows PLENTY, and it probably goes a bit farther than "two to the center of mass, count two; add one to the head if it's still moving".

Hey don’t forget SASS single action cowboy shooters, the three guns of the old west, lever action rifle, shotgun and pistol. I became more proficient with a firearm with 15 years in SASS that I ever was with 20 plus years as a deputy sheriff in law enforcement. There’s also three gun modern firearm competition that’s out there. Someone else talked about 21 year olds handling firearms, about 60 years ago in our history maybe more kids took guns to school and stored them with their lunch bags and their coats for protection to and from school or to shoot game. I’ve noticed that as far as our freedoms this country seems to be devolving.
