Thia is a tough one and obviously hugely controversial. There is obviously a problem within the force to some degree - almost certainly starting at the top and thus working its way down through the ranks, right from training and how to deal with all people equally from day one. Too many times, that clearly is not happening. However, I entirely agree with you that the police force is made up of people who are very often extraordinarily brave in an often thankless job. Collectively, the system needs work, but the collective is made up of good, decent individuals too who have only ever wanted to help, I am sure.
A brave write, and quite right for feeling free to speak your mind in such a politically correct time.
