Was that a combat roll or just rolling for cover because he was in too much shock at the time to get to his feet?
In any case that was a hell of a firefight. The big problem here is that the perp got 107 years in prison. With good behavior he MIGHT actually live long enough to see freedom. People like that should die - not be given a cushy cell for most or all of their natural life.
This is who we are, what we do.
