Well, we get called out for a mouth injury. Turns out it's a drunk guy from Newark who wandered over and got jumped. Abrasion to the forehead, missing a tooth, bleeding from the mouth. He's very agitated as we pull up, shouting at the cops (one monstrous officer and a sarge who seems just about done putting up with this guy.) When we arrive, he loses it. We calm him down a bit, but when we ask him to get on the ambulance, he decides it's a good time to start struggling with my partner.
Which is a mistake, because my partner knows how to handle himself and drops the guy by grabbing left wrist and neck and pushing. He almost gets physical in the bus on the way to the hospital (I was driving) but doesn't start fighting again until we try to get him to sit in a wheelchair so we can bring him in. Once more, he gets put on the ground, and at this point nobody involved has any more time for this moron. We wheel him inside, I go up to the desk to tell them to call security and get 4 point restraints ready. This is when I hear a bunch of yelling from across the ER and look just in time to see the patient take a swing at my partner and the cop. I go running over, one of our coworker EMTs is running after me, my partner and the cop floor the guy hard. I dive on top of him and put him in a headlock, and the skel gets cuffed. He's shouting about how he "didn't do nothin' " and the security sargeant is asking me if the patient is under arrest. I say, "well, he just assaulted an officer, so, yeah" and go about my business. We stand the guy up to walk him over to the bed, he pulls away from us, stumbles, and goes face-first into an oxygen cylinder. Busts his lip up, starts bleeding everywhere, but that took most of the fight out of him.
And that's the tale, as best I can tell it without visual aids.
