Dear Mr. Cheney,
The National Rifle Association is a group dedicated to gun safety. I think they also do some advocacy work on the side. Perhaps you've heard of them?
Anyway, they have a pamphlet with some rules for staying safe. I thought you might be interested in Rule # 1:
1. ALWAYS keep the gun pointed in a safe direction. This is the primary rule of gun safety. A safe direction means that the gun is pointed so that even if it were to go off it would not cause injury or damage. The key to this rule is to control where the muzzle or front end of the barrel is pointed at all times. Common sense dictates the safest direction, depending on different circumstances.
Boy, does this sound like a great idea! Bet you wish you'd thought of it before you tried to take off Harry Whittington's head with birdshot the other day, huh?
They even teach courses in this stuff. There aren't any in the District of Columbia, where you live, but maybe you could take a class in Virginia. Here's the list of classes. After all the embarrassment you've caused him, I'll bet your boss would pay for it. Or maybe Mr. Whittington would. Or maybe the Senate Democrats, now that know what you're capable of.
