Bricks are dangerous. Denney was on the verge of death after only two blows to the head. In fact, there is no age limit to owning a brick. No registration for felons either. And bricks are everywhere.
Bricks are cheap.
Thugs that can't afford guns can buy bricks. In fact, for the price of one handgun, you could probably buy 80 bricks. According to the Bureau of Alcohol, Tobacco and Firearms, there have been over 211 million guns manufactured in the United States since 1900. But compare this to the number of bricks. Today, according to the Brick Industry Association, there are 84 manufacturers in the United States, operating 204 plants, that make 9.4 billion bricks each and every year.
