This has nothing to do with airsoft and everything to do with bad parenting.
One, the kids didn't listen to their parents when they were told to wear eye protection.
Two, the parents of any of those children were clearly not supervising the activity.
Three, the parents bought the guns (most likely Canadian Tire clearsoft) for their kids, when the kids are way too young to be allowed to use them.
I honestly don't understand why these younger kids don't start at laser tag when they're young, move up to paintball, and then move up to airsoft from there. That's what I did.
