I might understand that the LEO was doing his job as he saw it, but I can still be pissed.
If I am driving a dump truck and I run over your car by mistake and I apologize are you saying that you wouldn't be pissed?
Dude I guess you can not read. I didn't say that he (or if it was me) should NOT be pissed off. And you analogy is not even close to what happened to the OPs incident.
Your analogy is left wide open for many things to have happened. The OPs incident DID happen and is not a WHAT IF. Again (at your analogy) if no one was in my Mustang, and you were fine, and the trucks brake were faulty, and you and the trucks owner apologized, and you both said you would pay for all damages and do...or pay for my new Mustang....then I can not be AS/TO PISSED OFF. Again this is only one of many avenues that could take place in your example...see how your example does fit. We could even add a death in there or two. Stick to the facts.
