Evidence that the Zero Tolerance approach on guns in schools is actually done to change students' views

Some evidence that public schools are actually trying to indoctrinate students on the gun issue.  There seems to be no notion that there are also benefits as well as costs from guns.  From the San Jose Mercury:

An elementary school will hold a toy gun exchange Saturday, offering students a book and a chance to win a bicycle if they turn in their play weapons. 

Strobridge Elementary Principal Charles Hill maintains that children who play with toy guns may not take real guns seriously. 

"Playing with toys guns, saying 'I'm going to shoot you,' desensitizes them, so as they get older, it's easier for them to use a real gun," Hill said. . . .

Every child who brings a toy gun will get a raffle ticket to win one of four bicycles, Hill said. . . . .  

Hill hopes the toy gun exchange idea catches on. 

"If we want older kids to not think guns are cool, we need to start early," he said.
