It is pretty insane to be using kamikaze explosive drones to kill civilians, gang members or not. A grim view of our own future perhaps, coming from a nation stuck in the stone age.
Shows just how bad the situation is for the MSS and police forces there, and if the gangs manage to even get one copycat attack off against the police (they have supposedly been caught attempting to purchase drones in the Dominican Republic for just that purpose), that'll probably cause an immediate collapse in morale. Then the bad times are over, and the Barbecue age can begin.
