I enjoyed it. I love how it also exemplified the hypocrisy of that one guy trying to discourage violent gaming, and there he goes with real life ammunition.
As someone who's fired live weaponry at targets and has dabbled into so-called violent games, there's a big cognitive difference when you have your barrel trained to something on the screen, in which killing a person will bring no actual negative repercussion or feeling of guilt to you, and training a live gun on a person.
While the digital person will come back with a restart of the game or will simply respawn, your mind kicks into a different gear when you're actually aiming at a real person. You know that with one pull of the trigger, you can end that person's life and drastically affect several others by that one action. You'll hear the person let out the moan or yell, you'll see the blood splatter, you'll smell the copper-y alkaline smell blood gives, and you'll see them die right before your eyes. It's a MUCH more traumatic experience. Anyone who can do this is MUCH more messed up in the head than just "learning it from a game."
I can really say, the last clip of the show spoke MUCH more about this than any baseless conjecture from Jack Thompson or some politician up on the Capitol. People aren't as two dimensional mentally as they may think. Firing an actual gun--the recoil, the smell of gun power, the loud CRACK that rings out upon firing, the feel of the weapon's cold steel in your hand--is much different from leaning back on the sofa/bed, a bag of your preferred snack food next to you, shooting at some soldier on the television that will just respawn later by the use of a controller which, at most, tickles your hand to offer "force feedback."
