All my life I have lived in communities where there are good cops. And why is that? It’s because I have lived in good communities.
Cops are just a representation of the people they serve. If you have bad cops, you live in a bad community. If you live in a bad community, you are more likely to vote for bad people. I.e. Democrats.
Pretty simplistic, and wrong, way of looking at it.
We have some bad senior military officers too - does that mean we live in a bad country?
