I propose installing Security Turnstiles in special places (Schools, Government Buildings, etc.) to protect citizens from those that might bring guns, riffles, knives or any firearm into a building.
Why is this important?
The gun issue may last a long time. Security Turnstiles would be a great deterant for thows who would inter a school or government building with guns or knives.
What if a teacher has flipped out. And deside to harm the children in a school.
