“The officer was trying to kill these people instead of apprehending them?”
Are you kidding? They fired 34 rounds at the cops. What did you expect them to do, discontinue the chase? They were already murderers! In this case, I’m just sorry one of them is still breathing!
I wasn't part of that exchange and just guessing, but I'd expect the lead car to back off a bit but keep the suspect vehicle in sight. Not only for the cops own safety but everyone else, in the hopes the suspects would maybe stop firing recklessly and indiscriminately at the cops. I would do this while requesting air support and coordinating ground units on exact locations and direction so as to quickly set up perimeter so when the pursuit ended there would be lots of ground support close by.
Btw, it really hard to hit anything from a fast moving vehicle, especially at another fast moving vehicle who's trying their best to evade you.
