Place US Troops or some sort of highly trained armed security in EVERY school in order to protect innocent children.

Let's place US Troops or some other highly trained and armed security in our US Schools so that our innocent children are protected. It will help deter intruders and students from attempting mass murders and security would be onsite immediately in case something does happen. Arm security with weapons, bullet-proof protection and access to security cameras. Security also needs to go through training to deal with people who are disturbed, upset or suicidal.
