Camden made all members apply for jobs as if coming from another police department, but they had the files of the old department and could look directly at an applicant's job history and see how many complaints of excessive force were present, etc. They purged the worst 25% in starting over and that seemed to make a very large difference.
'hiring more police' well that can be argued as exactly what the activists want. if you define police as individuals who help the community with their issues without violence. making sure homeless people get food/shelter, mental health issues are resolved non violently etc.
I'd be all for hiring more of those 'police'.
As for surveillance, depends on the kind. I'd be all for surveillance used for detecting gunshots throughout a region. less okay for audio/video surveillance on every street corner.
Have you actually gone out and talked to these people?
