First off, short-barreled, unstocked semi-automatic rifles are to "pistols" as moose are to deer. These are small rifles for practical purposes, being pistols only in terms of legal classification. It's a moot point; wear an overcoat and you can carry a large scoped rifle without notice. More importantly, any .223 round will pierce soft body armor and the steel trauma plate worn over the heart. I challenge readers to search ballistic vest manufacturers' web sites and find a vest that can withstand .223 rounds. Certainly there is armor that will resist rifle rounds, but no cop is walking around in it. He couldn't bend over or fit in a patrol car. This regulation is one more example of an intentional lie (BATF knows better) being foisted on an unknowing and gullible population to achieve a hidden political objective. If the BATF can restrict ammo by their regulation, as opposed to law, then the battle over firearms will be waged without a single vote. This is a political trial balloon and has nothing to do with the safety of cops.
