You mean like the one Chicago already has? I'm entirely expecting him and his cabinet to more or less try to pattern themselves after the policies of Stalin in the mid to late 1930's with the nkvd, disappearances, forced confessions, and show trials. His appointee for homeland security (king c00n) is basically advocating turning the jails in this country into Guantanamo bay and labeling protesters (most notably BLM) as terrorist sympathizers and terror suspects.
Edit: I think there's some 2.4 million prisoners in this country, some 22% of Americans have a record, and police in this country kill an estimated 1100 people per year while just 4% of them are charged with crimes when they commit them. My prediction is by 2019 there will be 3.2-3.5 million prisoners, 27-30% of Americans will have a record, and there'll be about 1600 murders by cops annually and I fully expect police to start killing protesters at protests. Hopefully I'm wrong.
