Probably because CPD came out and said all victims had gang ties. So now they are trying to spin it as the takeovers are all gangbangers which is the FARTHEST thing from the truth. Brighton Park is a fucking gang war zone and has been for many years. I've already heard what gangs were involved and not going to post it as it hasnt been released yet. But its 2 gangs that have been beefing over there forever. Its just a coincidence it happened during one of those stupid fucking takeovers.
I don't doubt that the gangs have limited involvement when running shit like that, but at the same time they're just gonna go get action where the people are. Group A sees group B and decides to get to work.
Happened in Joliet a while back too. Big party, bunch of people got shot when some rivals decided to settle scores.
I could see how it would be tactically advantageous. Your mark is a lot less likely to see you coming I'd think because of the crowd. That said, the risk of hitting third parties is higher as is the potential for more witnesses. If you care. We're getting to the time of year where heavier, more concealing clothing is not out of place though. If it comes out that a single gang had 3 people killed and 2 injured this would seem to be a hit job, and fairly well executed at that.
