The criminal element possesses many illegal items and does many illegal things. That's why we call them criminals. Ever wonder why you can't move more than $10,000 in cash without filling out some forms? (If you're lucky enough to be able to round up $10k, that is.) It's the "arms" and "people" that are the cogent parts of the text here. Current activities are centered around defining arms, my point is "people" should include police and other similar bodies. You're point about criminal oppression will no doubt be brought up by the police if the idea above is ever proposed. "We will be at a disadvantage," will be their take. The response is, "So, why should you be any better prepared for those threats than WE are?"
