The chase was well called out by the pursuing officer, I have to say. The shooting, in my humble opinion, justified. It's too bad police had to down two police cars because of this idiot.
Should the police have chased? No. They rarely should. And particularly not when you know the identity of the suspect and where he lives! (And it's odd to me as a former police officer that the the pursuing officer is never ordered to call the chase off. Instead the suggestion of calling off the chase is offered a few times. I know -- right or wrong -- that I would not have followed that "suggestion." Why? Because as a cop I want to catch the crook. And as a guy, car chases are fun.) What do you want to bet that police in Ames, Iowa will make a more restrictive pursuit policy very soon?
But the moral? I think it's rather simple: don't call police to teach your child a lesson. Seriously. That's not what police are for. Why, because your child might be a fool and end up getting shot. (Also, it wastes police time). [Update: to paraphrase a comment below: "You play stupid games, you win stupid prizes."]
From Salon: “He took off with my truck. I call the police, and they kill him,” James Comstock told The Des Moines Register. “It was over a damn pack of cigarettes. I wouldn’t buy him none.”
You wouldn't buy your son a pack of cigarettes and he got pissed off and so you called the police to report a stolen vehicle?!
