Yup. Not seeing a lot of discussion that the thug in question actually may have had a gun, too, as possibly shown by some vidoe from the incident.
It was a dynamic situation and perhaps could have been handled better, but he was in the midst of making an arrest. What I see is a cop not handling the situation perfectly, then feeling threatened, he draws his gun not knowing if those guys are part of it, he keeps his gun pointed down and then holsters it as soon as he realizes that the potential threat is gone.
