Make some type of NPC aggressive

Hi everyone, i’m here because some friends of mine want to run an RP military server where a part of the population is agressive against the military force. But we have a problem, how can we make that all gangs in the city are agressive, shoot on sight even if we don’t shoot.

SET_PLAYER_CAN_BE_HASSLED_BY_GANGS(player, true/false)

under 20 char?

Where do we do that at?
