breaks arm

I scampered low around the passenger side. The passenger window was still down. I watched the side mirror. The guy inside saw me. The gun came out the window with a tranq dart loaded, but now I was behind him and he didn’t have the angle. The guy shifted in his seat and his arm came all the way out and I stood and pulled his arm into my hip and yanked back hard. His elbow dislocated and I heard his humorous fracture with a muffled crack.
