Re: CO2 hurts
Noone mentioned the fact that paintball guns should never be shot in the direction of people not willingly playing paintball or wearing a mask?
Using markers in this sense is how paintball keeps its black eye.
"If society is tranquil, it is not because it is conscious of its strength and its well-being, but because it fears its weakness and its infirmities; a single effort may cost it its life. Everyone feels the evil, but no one has courage or energy enough to seek the cure."
