I didn't have any audio with this video, as this would give me much more insight as to what, if any, verbal directions the officer gave to the suspect.
An officer should never WANT to wrestle with a suspect. Their goal is always to get back up and place the suspect under custody. Ok, that was accomplished. The suspect was on top several times in the encounter. Unless I'm missing something, his offense did nothing damaging to the officer.
The officer was using his legs at different times to keep space between him and the suspect. To those who always slam an officer for being "gassed", I offer you this. You try wrestling on pavement wearing 25 pounds of equipment, a kevlar vest that restricts breathing, in a polyester uniform and jacket, with insufficient sleep for the past week, and see if you get "gassed." It's much different than wrestling on mats, wearing speedo shorts and wrestling shoes, in a 72 degree room.
That's why an officer needs to get back up and not wrestle. Did the officer do a textbook example defense? No. Was the suspect subdued and the officer go home safe to his family at night? Yes. Job accomplished.
