Just remember kids, when it comes to weaponry, leave the armoury at home or the local authorities will take away your toys & freedom. No fair!!! No fun!! 
Indeed, we traded freedom for comfort and safety. We need to get it back and certainly teach children not to inhibit a wussy type of character, are you going to be a man? Or are you going to be a grown up boy? Teaching kids how to handle violence with Morality in the mix helps them become better individuals than what society believes.
