I think you could be correct, and this will not deter them from electing a democrat.
My theory is that these people are used to the murder and violence much the same way a hardened combat vet is used to the combat environment. Soon it becomes a way of life. People know who the good guys are and the bad guys and adjust accordingly. The Chicagoans are born into this and know no other way of life.
The difference is the incentives the rat party offers, which is likely payments and projects that benefit the inner city crowd.
This is my theory. To back it up I met a young black girl who felt unsafe at Minot, ND because there were no sirens going off such as police and ambulances. The sirens told her she was being protected. This is a sad way to live.
