Well, anybody that would try to conceal something like either an AR-15 or AK-47 type handgun would have to be a complete idiot anyway. This is all just BS camel nose under the tent stuff to do backdoor gun control. Even the (honest) cops know that they aren’t in any danger from this stuff.
You hit the nail right on the head. The fact remains that any .223/5.56 ammunition fired from an AR pistol will penetrate Level IIIA soft body armor worn by police under their uniforms. Banning M855 does not increase police safety in the least.
