Gorden arrived just as the fight was going on. He saw Red arrow on the scene. Ok so batman might have brought in some help. Gorden went on the radio. "Ok, I want everyone to avoid the big clowns? I repeat only retain the normal members of the jokers gang. Be careful that might have something on their person." Gorden put the radio back in the slot seeing the batman take down the massive clown in his usual brutal manner.
