In some school systems, just pointing a finger and going bang can have a child removed from school. In this day and age, just carrying a stick could land a boy in trouble with someone; there will always be someone whom will complain. Safety is the concern, or is it the possible expose to violence that is the real concern?
Some of the survival skills and outdoor lore has skip the knowledge of hunting, uses of spears,slings, bows, throwing sticks,etc...When I was a young scout, we set snares for rabbits,gig for frogs, caught birds in nets ( which we made) fished, and gather edible plants on a hike/or camping trip, lived off the land, but we carried sheath kniives, hatches, Thumbstaffs, but that was awhile back. Times changes, let one boy be harmed and see what the real gray area is.
