Honestly, I understand him killing himself. In the same scenario, potentially facing 15-25 years in prison for a felony (being white would likely help keep him out of jail, but being a geek with aspergers would not), I would likely do the same, as in the US there is no life after prison.
This is interesting, actually - unsurprisingly, the US is the most punitive place on earth if you assault a cop, although I can't see how you could assault a cop in the US, given that they're armed to the teeth and usually in full armour, and usually sat in an armoured and armed vehicle.
