White People Bad
I expect this to be nothing more than a sensationalistic Hollywood infomercial that vilifies white people.
To be sure, their were racial tensions at the time, never more evident than between black people of Detroit and the DPD. But all black people were not criminals and all cops were not racists.
It didn't get better after the riots with "White Flight" from the city and the creation of S.T.R.E.S.S by the DPD.
