I'm not saying I sympathize with him or that murder is ever justified; I'm merely speaking on his own mindset that he's carrying out "justice" on a corrupt system. In that case, I don't think he'd really care too much about the death penalty or ending up in jail...his claims are that his goal is to "clear his name" and expose the LAPD for being corrupt.
But, like I said, his apparent "goals" are totally negated because he just randomly killed a bunch of innocent people. And, after reading his passage online, he really just seems intent on "clearing his name" which is also quite bizarre considering mass murder isn't exactly the greatest way to go about doing so.
It's just strange because in some cases he seems like a guy who knows exactly what he's doing and is trying to accomplish something (while going about it in a ghastly way), but in other cases he sounds like a complete nut job with random shout outs to celebrities and insistence on "clearing his name."
Hence, the story is interesting.
