Yeah really. You cannot control the actions of individuals. Having rules in place, and doing what you can to have control points in place is all you can reasonably do. Someone bringing a laser into the game when they are banned isn't a matter for insurance, as that individual is responsible for anything that may happen, not necessarily the game organizer.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
