I know the precinct captain for one of the wards on the South Side of Chicago, and he says that most of the cops have just given up now. There are a few bad apples out there, but his guys are fed up with being protrayed as racist, before they've even done anything. Regardless of the socio-economic antecedents of a predominantly low-income African American demogrpahic, the fact remains that the vast majority of gun crime in the city is black on black. He claims that previously, his guys would be flying down to any calls regarding gun shots, but now, they just don't want to put themselves in harms way any more, in case they get embroiled in an incident which ends their career. As a result, shootings are up 100% in Chicago this summer.
Regardless of where you fall on the politics, and this is coming from someone who is very left leaning, anti-gun, pro civil rights etc, this is not a situation that benefits anyone. I know a lot of cops, and nearly all of them are great guys, doing very stressful jobs. The situation is becoming completely untenable out there for some of them, and I fear things are only going to get worse and worse for both sides.
