All I stated in my earlier post was that private citizens did not have sovereign immunity. I don't know of any state that gives peace officers a different standard on criminal liability.
However no state gives a private citizen intervening to stop a crime in progress (which this wasn't) sovereign immunity. Any civil action is on the private citizen. Some states extend it to private citizens who are asked by a peace officer to assist. But if you act on your own, you're on your own in court.
In this particular incident, if a peace officer had opened fire on the car he could face the same criminal charges, however in the inevitable excessive force lawsuit, his employer would be the one who is held liable.
Even if he escapes criminal prosecution or is acquitted of any charges, he's going to be on his own in civil court.
