Metropolitan Nashville Police Dept. (NASHVILLE, Tenn.) -- Security video from inside Covenant School in Nashville, Tennessee, captured the suspect entering the main school building unabated by blasting through two sets of glass double doors and stalking the halls before killing six people, including three children. The security footage, released by police Monday night, raises new concerns over whether schools should have fortified or metal entrance doors that could have deterred or delayed the suspect's entry.
