The guy shot and killed a kid for walking on his lawn. In my opinion that qualifies for freak status.
This reminds me of the Crespi murders, wherein the Wachovia guy murdered his young twins daughters and we had a spate of people posting their sympathy for the child killer.
I didn't claim that he did the sensible thing. But I think it's probably more about that he "freaked," rather than he's a freak.
I don't see any comparison to the other case you cited. IMO, you're stretching to make your point.
You know, I was keeping tabs on the Crespi case to see how it's prosecuted and just in the past few days, there was an article saying that David Crespi had just changed his anti-depressant two weeks before the murders, from the Paxil he had been taking, to Prozac. He said the Paxil made him gain weight.
