First, I know everyone on the site has voiced every opinion possible on this subject. I'm just throwing in my two cents.
If my daughter had, several times, wasted my money and treated me like a slave driver despite a fair amount of leniency and a moderate amount of familial responsibility, and slandered me many times in public, she would deserve the loss of privileges. If she had done this with the laptop I bought her, maintained for her, and put an unnecessary amount of love and effort into, then she would deserve to lose it. The strongest way of doing this would be to destroy it in a way that she could not ignore. Whether by gun, knife through the screen, torching, snapping it in half, or smashing it, thhe same message is conveyed; "you will not be doing this shit again, since your computer is dead."
All the problem with the tool of destruction being a gun is really a pointless nitpick. The gun was fired into the ground, in an isolated area, into a stationary unliving target. A hammer would have done the same damn thing, except minus the cost of bullets. I go target practicing all the time, and have even shot up old CRT TVs and PC monitors. While angry, he did not go ballistic. No one was hurt, no one could have gotten hurt. He wasted money by firing those rounds, but that was his choice. The only rationality behind the shooting itself being reprehensible I can possibly think of is the "Oh no, guns! Once those things come out, they can't be sheathed again until they taste blood! RUN!!!" argument I hear so often coming up in the gun control debate. No, the issue at hand should be whether it was wrong to post his punishment of his daughter on YouTube, or even whether destroying her laptop was wrong. And that is simply the difference between accountability-based parenting that focuses on consequences for misdeeds and... that other kind of parenting that teaches that the child can never be punished with more than a dissatisfied look. Could he have simply pawned off the laptop? Yes, yes he could have. Could he have simply not posted the video online? Once again, yes.
Also, a lot of you seem to actually believe the girl's facebook post about having to do all that housekeeping. For you all, ignnore the above post since in your eyes the dad is wrong anyway and just did something even worse.
