Sheesh, I remember at the turn of the '60s/'70s, we used to play "Get Smart" at recess. We ran around quite happily, pretending to shoot each other... using a stick, a banana, or our bare hands for "guns." The teachers took not the slightest notice of any of it.
Wow. If that was forbidden here, all children aged 7-10 and many above that age would be in jail.
