Are you trying to address universal commonalities in police work? There are very few of those. What is your metric for defining "winning"?
There are some commonalities that need to be addressed in the way police work is done in low income, high crime areas, especially those with high percentages of blacks. We talk about making those areas "high enforcement" but in far too many neighborhoods that is not the case. Police response is slow, and there isn't enough presence to deter crime. Without that presence and relationship with the community, police are ineffective.
The greater problem is the system that enables and sustains poverty, ignorance, violence, racism, and dependency. Winning is breaking this cycle. The politics of that cannot be solved, or even explored here.
I do not blame law enforcement for creating this mess. There are individuals and departments that contribute though. Denying that ignores the evidence. I know many cops, some well. I respect them and the work they do. They are professionals who are dedicated to serving the community, putting their life on the line daily. I also know that there are others who should find another line of work.
