Chicago is going to try an experiment to notify possible shooters and victims of "gun" violence. It is profiling, but profiling backed up by sumdood a professor from Yale with a degree and shit. So the short story is that they are going to send a team of cops to gang members known cribs to tell them to not shoot people. Or else.
I'm a little confused, it sounds like they will also be warning the possible victims, too. That will go well- guy who is suspect with his peers getting a visit from the cops. Or maybe they will just warn people on the CTA with iPhones.
