Asked and answered, what, 6 times already? If you consider no immediate effect = no effect, then, sure, who cares?
But in 1982, the 7th Circuit ruled that "arms" do not include handguns, and now the cities of Chicago, Morton Grove, Oak Park, Evanston and Wilmette have used that to ban handgun ownership. Not "disassembled", not "with a trigger lock", not "room-to-room". A total ban.
Recently, a homeowner in Wilmette had a handgun, used it to shoot a burglar, and the homeowner was arrested.
What if they did, indeed.
