Maybe you should watch it again, he had more then one round left. And using a weapon isn't to be taking lightly. See what can happen when you don't concentrate while operating a weapon.

Trust me, don't ever take gun ownership lightly. That last guy's been shooting for 14 years. All these accidents only took a "brief second".
The first guy and the third guy made the mistake of putting their fingers inside the trigger guard when drawing their weapons, and accidentally put pressure on the triggers as they lifted them out of the holsters. You can do that with a single action revolver with the hammer already down, but if you try it with a double action weapon, one with the hammer cocked, or an automatic with a round in the chamber, you are asking for trouble. Neither one of those guys seems very intelligent, based upon their speech.
The DEA agent forgot one of the most basic rules of handling a firearm, which is to always handle it as if it were loaded and ready to fire. I suppose we can be thankful he only shot himself in the foot, and no one else there. You could see and hear the unrest in the audience when he continued his speech after he shot himself. If he actually got his hands on that carbine, I'm sure at least half of the audience would have made for the door.
The dad of this girl was stupid in how he handled this. If he wanted the computer to be gone, he should have just sold the computer, and gotten some money for it, instead of throwing money away by destroying it. It would have gotten his point across just as well, the computer would be gone, and he would have saved himself some ammo, too, and not had to clean his gun after. *******.
Incidentally, the child has no self control, and it seems the parent doesn't, either. It seems the apple doesn't fall that far from the tree, after all.
Just noticed he was a smoker lecturing his daughter about common sense when people have known cigarettes cause cancer since 1964. Way to go on that good example of common sense he has set for her all these years.
Also, he doesn't have the right to destroy her property to make his point. She could sue him for the cost of her computer. Now that he made a video of it and admitted he was destroying her computer, she has the ammo.
If this guy will use his .45 to destroy his daughter's computer because of things she said with it, what else is he capable of? A man who lacks self control and owns a .45. Hmm...
If he had been there to raise her when she was growing up and given her proper guidance she would never have turned out like this. He has himself to blame for how she turned out. Interesting that she has a mother and a stepmother, too. Apparently his judgment in women and his people skills have been lacking. So he tells his daughter what to do by giving orders and expecting her to follow them. Something tells me he hasn't been around enough when she was growing up to create an emotional bond compelling enough to make her WANT to do as he asks. His daughter's behavior is proof of his failure as a father. She is her father's daughter.
