It is unfortunate that the civilians were injured. I can't arm chair quarterback that one. We don't know the details. Was the driver ordered to stop and didn't? Police in that area were definitly edgey knowing a trained individual was specifically targeting them. Again, can't judge without being there.
As far as burning down the house... It wouldn't have been the cops call on that. Fire and EMS are trained, scene safety first. I personally wouldn't have advanced a hose line anywhere near that house knowing a killer who had been shooting was in there. I have been on situations very similar to that and we did exactly the same thing as the fire department did this time.
I'm just glad that there will be no more dead cops because of this
