This Original Post reminds me of why I applauded the caning of that American Punk over there in Singapore a few years back. They don't seem to have this type of problem over there. Oh yeah, they have other issues, but not so much anti-civil hooliganism.
Paintball games are fun. You go in knowing it's gonna hurt. You can pick your level of intensity, too. Random shooting of peds or cyclists or anyone not interested in 'joining the fun' is assault. BTW, that wound doesn't look like a frozen ball - that's what can happen to exposed flesh at close range. Especially if the squid turns up the pressure valve. Happened to a guy I was P'balling with. He ran up to the shooter, smashed his custom P'gun, and kicked his punk ass all the way to the parking lot. Literally threw him a good part of the way. Nobody interferred. When the pressure is turned up, they do sound like gunshots.
To bad you couldn't get a license plate, but I understand you were otherwise engaged. Those f***ers know they can get away with it.
EDIT: I now remember that the squid's buddies were rounded up and also kicked out of the range. When thay saw that their leader had made an early and unplanned exit with the redneck truck, they were told by the proprieter to walk.
