Josh Powell Explosion Video?

Anyone can find a video of the explosion provoked by Josh Powell on youtube? I just can't believe this happened! What was wrong with Josh Powell? How can he even think of doing something like that to his little kids? I was told that the explosion was caught on video and that someone put it up on youtube.
I thought Josh Powell was guilty but I never ever imagined he'd be so insane to terminate his children! How did the police never see this coming? They never even sent him to a shrink, There's no doubt now that he is responsible for his wife's disappearance.

I've found the video that doesn't necessarily show the explosion that Josh Powell started but it shows some of the data they got from the incident. Here's the video.

Personally, I think people like Josh Powell should be in prison, it's a shame he didn't survive. This shows us how screwed is our system; known criminals just walk free because of reasonable doubt?
What Josh Powell did with the explosion is just barbaric, I can't believe he had the guts to do it.
