As a North American who has contended with public transit in many different cities on this continent, I can tell you, you should infer that a person making comments like this has been primed by conservative media to: fear everyone who isn't exactly like them, overestimate the crime in cities, demand a fascist police state, blame the victims of circumstance (and be blind to the systemic issues that put them in said circumstances), blindly dismiss any honest attempts to fix the underlying issues as "communism".
