School security ten years after Columbine

(CNN) -- In the wake of the tragic shootings at Columbine High School, some schools across the country turned themselves into near-fortresses.

They installed metal detectors and security cameras, banned backpacks, required students to carry IDs and posted police in the hallways -- all in the name of keeping students safe.

Now, 10 years after those highly publicized shootings in which two young men killed 13 people and themselves, school security has taken another dramatic turn.

Some of the noticeable security measures remain, but experts say the country is exploring a new way to protect kids from in-school violence: administrators now want to foster school communities that essentially can protect themselves with or without the high-tech gear.

Give the kids guns so they can defend themselves. I'm going to Hell.
