I suppose the investigation will reveal a LOT - as in, who dropped the guy off (or did he leave his car parked by the side of the road)? How did he time the run to coincide w/ the incursion? Was there any sort of instrument/weapon/etc in his hand or does it appear to just be an attempted suicide?

I'm often somewhat hesitant to lump simple silliness and/or mental illness into the terrorism bucket but this one is interesting...
