Oh, this is the part where we pretend a shooting incident would have happened even if there weren't Guns available ?
Well in this case it's true, I read that it was a last minute decision to take a handgun, he originally wanted to charge a crowd with a 600 lb sworfish strapped to the hood of his car, luckily for everyone, the price of swordfish is close to $40/kg so all he could afford is a semi automatic handgun. Whew. Dodged that bullet, err, so to speak.
