All you gotta do is Run around "Yelling Hands Up& Die" Then you shoot anyone who puts their hands up,Since you did warn them that putting their hands up will cause their death.Problem solved,If it's trolls you get a downing gun & Ziptie them,Dont even say anything just start shooting,It's non lethal so its not RDM(Random DEATH Matching) since no one died,Then once they are ziptied You take them to a dead end street & when you got 3-4 you get a SUV or a Hatchback & ram them Full Speed.Viola.
But seriously,RDM is like sex with Kobe Bryant,No matter how much you don't want it,It's gonna happen.
