surely if the rules state no staining paints, and the organisers allowed paint to leave the fields and enter the designated parking area then u got a claim against them for damages, oh an beware Tcut, it does exactally that, cuts the paint/removes a layer, use sparingly 
But as for paint staining jerseys, WTF its paintball, next you gonna complain of grass stains and muddy boots!!!!!
