We can not predict what evil will do, when, or where..if someone wants to cause mayhem they will..either with a gun or with a blade. All we can do is be prepared for anything. I hope to see armed personnel in our schools very soon. Not cops, but soldiers with AR15's. I don't care how unlikely it is that someone will strike. I want every child protected. More so than the president. Its a new world folks. Long live the Republic.
First the US Military doesn't carry AR15s the standard issue weapon is the M4. Second having lived through 9/11 and seen for the first time in my life US soldiers equipped with rifles inside PDX I'd really rather not see armed US soldiers in the schools.
