First of all age limit wouldn't do anything kids would just have their parents buy the guns. Second of all most of these pranks are done my high school or upper middle school kids who would be viod of the ban so really what we need to do is get rid of the kids who do this.

Age limitation is a serious business, although most of us are under 18, parental consent is a major thing. It covers the fields legally, there's a lot of measures they must make, since teenagers can't enter a legally binding contract, saying that they won't sue, the field need your parent's permission. I sense that you are just blowing off steam, please come back when you are calm. Thanks.
