airsoft in Canada
or any number of things
Add to that the fact that the guns themselves come with warning images in the manuals stating not to use them in public and not to even carry them in public. The fact that they had to get their parents to buy the guns should have given a message in and of itself.
I say ban them from games and the entire airsoft community, period. If they found buyairsoft.ca then they had to have come across ASC at some point or some site that explained even the basics of not showing them in public. Getting them criminally charged would be great, they get more of a second chance then they deserve as their criminal record is wiped out when they turn 18 anyway. It would be great if their parents could be charged but douchbaggery is not a criminal charge in Canada.
Canadian law even specifically states that ignorance of the law is NOT a defense.
