They would need to hire too many replacement cops. From what I hear almost half of the cops are racist and joined primarily because the KKK is going out of business.
There won't be enough cops period, as according to the MSM, all cops in America that are white are 'racist' or biased, or 'murderers'. Latino and Asian officers the MSM will also brand as 'white', and therefore 'racist'.
So all that would be left is a few Black cops who are meant to just flop over and die rather than actually fight crime. Because the MSM will accuse them of brutality if they use any kind of weapon to defend themselves.
Thankfully the MSM doesn't run America, or America would be as lawless as Somalia.
