If you were strangled on the subway how long would it be until they arrest your killer? Or would they arrest him at all? give him a medal?
Maybe you have no criminal record, maybe you have been paying rent. Maybe you are a pillar of your community and help at the local community garden. But maybe you aren’t white, aren’t Christian, or have “radical antifa” ties online. Maybe you live in a “bad” neighborhood (or like me in a good neighborhood that outsiders assume to be bad)
