Bad Ideas for Defense

Principal: Students Can ‘Hurl’ Cans Of Corn at Gunmen As ‘Last Resort’

Will there be "canned corn safes" where these will be kept? Will teachers be trained in their use? We don't want students to get their hands on these, they might be used on each other or on teachers! Letting canned corn into the schools is a slimy slope! (Recycling my own joke from Ace this morning.)
