What, we're supposed to give the guy a break because he's a geriatric?  Bullshit.  If it was any of us, they'd throw the book at us.
wikipedia shows some witness accounts:
	Quote:
	
	
		| * Seeing no brake lights on Weller's car; * That Weller stared straight ahead as he drove through the crowd, victims flying over his windshield;
 * That Weller avoided parked cars to the side of the road, steering instead directly down the middle of the crowded street; and
 * That upon exiting his car, cane in hand, Weller casually asked how many people he had hit.

 Somehow, he had the common sense to avoid the parked cars and continue to run people over.  Fuck him.
