I'm a bit confused about the taser thing. The DA said Rolfe knew he discharged his taser twice. Problem is Brooks took Brosnan's taser, not Rolfe's. Here's the footage of the struggle:
Truth be told, from the footage I can't really tell if Brosnan ever had the chance to discharge the taser before Brooks took it. When Rolfe used his, the discharge was pretty loud and noticeable. I think the defense could reasonably claim that during the course of the melee, Rolfe had no idea how many times Brosnan used his taser.
