Armed citizens stop criminals every day. If such mayhem were really occurring don't you think the oh-so gun-friendly press would let us know about it? This myth about "spraying bullets" and "friendly fire" has somehow taken hold in the minds of some, but there is really no evidence for it, at least in the context of gunfights involving law-abiding citizens. Gangbangers are obviously a different story--they don't care who else gets hit. We do.
