Some of the black gangs have initiation rites where the initiate has to commit a murder. That’s garden variety for many black gangs.
Some of the Hispanic gangs take even that up a notch. Not just murder-murder of an “innocent” (which in gang-speak means not affiliated in any way with another gang). Not just murder-but sadistic violence and murder. Not just the world and the flesh-but, quite literally, the devil-literal worship of Satan.
I would bet a bottle of Mescal the so called victims were not innocent.
