That should be easy to prove. Do so.
But I don't believe the real problem is the toy guns. The real problem is what people use them for: Games.
Games involving small unit tactics.
In other words: War games.
Having people armed in accordance with the Second Amendment is one thing. Having them well versed and practiced in the collective use of those arms is something else.
Yup. Oklahoma invasion. Great fun! The Chinese supposedly use them for training? That may just be a selling point, since these stupid guns break down, have rechargeable pain in the ass batteries, the bb’s are all over the backyard (pollution!). But it was worth it.
“The real problem is what people use them for: Games.”
How is that a “real problem”?
And what might that "something else" be? You cannot ban knowledge and what do you propose to do with retired military officers? Lock them up when they leave the service?
