All three of those cities are warzones, and the ones attacking these officers wouldn't last half a day doing their job.
If I were an officer in Chicago, I wouldn't do a damn thing and I would collect my paycheck. That is what the Democrats who run that city want anyway. I remember Beetlejuice lived on the safest street in Chicago because she had the police make damn sure that it was. As for the rest of the city, anything goes. Chicago is a trainwreck, and everyone knows it.RIP Ryne Sandberg.
