It doesn't strike me as an insane person... more like a guy that is crazy to get out of prison and see his family, no matter the cost. That's perfectly sane in my books.
Very true.
As for the paper, I agree for the most part. Problem with society is, a lot of people are morons and when you get the church involved into the equation, long story-short, you fuck shit up. Truth is, violent behavior is directly linked to one's evironment and experiences growing up. Quite an example of this type of media frenzy is the case of Richard Ramirez, a rock fan who also happened to be a serial killer. Problem of this type of cases is the media will automatically blame the music for his behavior, blatantly ignoring the fact that his life had been tainted by murder and was an avid drug user (not that drug using is a necessary catalyst for murder). In other words, the problem is not the music itself, but the psychological aspects of the person. The person's choice of music is only coincidental (and/or) consequence of his already formed psychological scheme.
If anything, this type of music serves as a therapeutic tool for some people to blow off some steam.
