So, from the sounds of the last 5 minutes or so of the episode it sounds like Scratch and her people were able to take the SWAT vehicle, as well as the guns.

I'm guessing Scratches people just shot the fuck out of the inside of the vehicle and assumed that Saul, CJ, and whoever else was in there were dead. I mean when Saul is barely talking to Lizzy through the radio you hear Scratch in the background say "Get the guns inside!" So I'm thinking CJ and whoever else was in there are dead, Saul is seriously injured, and Scratch just got an armored vehicle and enough guns to arm a small infantry unit.
