What worries me, what has always worried me, is that the idiots that run our country don't know how to think for themselves. They have a knee-jerk reaction to .50BMG. Suppose they were to outlaw them. Nothing to keep someone from developing nearly the same capability in a slightly smaller caliber, say .458. So they out law the evil .458s. Time passes. Anything .45, then .40 and above becomes illegal. More time passes. 9mm and above becomes illegal. Then its .30 cal, .25 cal, .223. At that point society will have to deal with the dreaded and evil .22LR sniper rifle that can take out an airplane (Cessna at point blank range), shoot through concrete (well, it may take hundreds of rounds, but eventually you should be able chip through), and shoot a bullet over a mile.
Aaargh! [rolleyes]
