Love the pseudo-intellectual libertarians who just roam the interwebs looking for the next best "gotcha" brutality video that usually shows 0 context that stars an irrational person who is trying way too fucking hard to contradict a police officer and sounding incredibly stupid/abrasive in the process. There are thousands of interactions that take place every day that don't involve officers saying, "I'll put a round in your ass so quick."(which I agree with you isn't the optimal way to deal with the public) As Hexen said, I feel like these ultra-violent instances happen very rarely.
You automatically excuse yourself from this conversation when you ask for oversight and accountability for improper police actions and yet write off an officer's suspension as some borderline conspiracy-theory saying that, "he will just be reinstated when this all blows over." You're so obviously pushing some far-right anti-government/anti-police agenda. Lets all remember that you and your cohorts propped up Cliven Bundy as some kind of champion of liberty.
You're using this Ferguson situation(as well as the last video you posted), which is more about racial disparities and inequalties than whatever militarization/NWO/coup d'é·tatplots your agenda is trying to push.
