This just happened:
As soon as I heard where in the city this happened and what school it was I knew it was gang related and outside the school rather than the horror of the "other" kind. Small comfort in that but they didn't even have to tell me that it was possibly gang related, I already know it was. Naturally, there is a chance that could not be true and all other schools in the area are on lockdown because of this incident, but just as a resident with a feel for it I'd say he's long gone, and it was more personal, even though it was still crazy, pointless and horrible.
I can only hope one of the kids shot can identify the shooter and that "snitching" being a thing to avoid will not come into play here. I hope they know who did it or can take a good guess and will be very willing to talk about it.
I feel sad because this part of town has a reputation and that's too bad. Lots of working, normal citizens in the area, not just thugs and drugs.
