In case you aren’t aware, people can only hold a couple of jobs and one time and it’s ok for them to critique policies and actions of people in jobs they don’t have or ever intend to have. I can criticize a politician’s performance even though I don’t ever intend to become one. There is nothing illogical or hypocritical about this.
in a democracy, if you point the finger at something and come to a bad conclusion, and then demand a ridiculous, unworkable solution, it is my duty as a fellow citizen to inform you and other voters that you are extremely wrong! That's what I'm trying to do. There's actually no super policeman hiding out there that can do what you say, and guarantee that across a population of over 300 million people there will never be violent interactions between the police and the citizenry. It is insane to suggest that.
Clearly you are incapable of a reasoned, nuanced discussion on this topic. You should try reading what has been written dispassionately. No is suggesting that there should never be a violent interaction between police and suspects. Clearly the discussion at had deals with police doing things like torturing suspects (read about Chicago police and death penalty cases there), and beating apprehended and subdued suspects.
You are taking what is written and applying an interpretation that clearly is not intended or made. You act as if those wanting reform seek out the most extreme, nonsensical standards. You are unreasonable in your responses. I hope for you that you may one day learn and understand logic and nuance.
