27 year old 2 bit thug may have had former military experience and lots of remote range time. Not all gang bangers are spray and prey wannabes. Some can shoot !
I guess the lesson is, assume they ALL can shoot. And because they CAN shoot, give them the best-trained, most deadly accurate, and concentrated counterfire from behind cover that can be offered. All of them. Even the greenest gang banger. Don’t attempt to arrest them. Take them out.
That was my first thought after wondering how one guy could have done so much damage.
I wondered if it was one of those gang bangers who joined up specifically to improve their skill set. Not badmouthing the military here, but it does happen.
I hear that it’s happening an awful lot lately.
