This is clearly an over-reaction and is complete BS. How are we supposed to teach our children about history and events that are currently happening around the world when we can't bring a LEGO gun to school? I can see it now. Some poor student gets assigned to do a presentation on the Civil War, and he decides to build a scale model of the Battle of Gettysburg as a visual aid. He gets suspended or possibly expelled for having teeny soldiers with their teeny rifles.
When I first read the title, I thought that the 2" gun was something like the "Swiss Mini Gun" Introducing the world's smallest gun that fires deadly 300mph bullets - but is just TWO inches long | Mail Online, which is 2" long, but after seeing the photo of the little Lego policeman holding what is CLEARLY a toy rifle, am appalled by the response of the principal. Examination of the item would reveal that it has no moving parts, cannot be loaded, and most certainly cannot be mistaken for a "real" gun by any stretch of the imagination.
I seriously wonder about the intelligence of the school principal.
