Wow.
Still seems a bit weird.
“Gang member” memorial…I.e., Demographic, most likely #1.
But, the style could indicate Demographic #2.
My gut was Moslem except not usually that many at once, and usually include themselves in the slaughter. And of course, “gang member” means likely not Moslem.
Dem#1 never really does a whole bunch apparently coming up with a plan to surround or such. Sounds more like Dem#2.
