How about the "fact" that the cop may have decided not to risk pursuing this upstanding citizen, and instead went on to ticket some dangerous j-walker, then later found out that upstanding citizen went on to plow his car into a bus load of school children?
Was excessive force used? Maybe, unfortunately that's up to others to decide. As for the question of putting others at risk to pursue a ---cleveland steamer--- head, I agree that this is a debatable topic, but that’s for another discussion. However IMHO the cop(s) made their choices, just as the driver did, now they all have to live (or die) with their decisions, and we all get to breath a sigh of relief that another criminal is off the streets.
