I'm really not sure what protocol you want the police to follow. They were simply responding to a call about a shoplifting suspect, got a lead on the vehicle ID, and did what they are paid to do and attempt to apprehend the suspect. There is also no way they could have known at the time what the relative value of the stolen goods was anyways. Besides, how is that even relevant? Would it have been more "worth it" that a guy died if he had stolen $1000 laptop instead of $50 of miscellaneous equipment? If not, what if it was a $10,000 Rolex? A $100,000 sports car? If he had kidnapped somebody? The answer to all of those questions is hell no, it would not be worth an innocent life. There is no logical break point at which you can say above this threshold, the juice is worth the squeeze and below it, I'll just get him tomorrow. We unfortunately live in a world of criminals and sometimes they make rash decisions that cause collateral damage. It sucks, but its the world we live in. You can't place any blane at the feet of those who are trying to catch the people making those decisions.
