There was a fence, automatic lockdown doors, and an armed guard posted at the school. The gates were open to allow for buses and cars to easily come and go for pickup (procedures requiring individual checks at guard gate during pickup would cause major delays in buses and parent pickup, I doubt it will go over well in large schools in metro areas). The automatic lockdown doors were overridden by the shooter pulling a fire alarm. The system was already scheduled to be upgraded to prevent this, the cost was $900,000 (I doubt states and counties have these kind of funds readily available to upgrade all schools). The armed guard was not at the school at the time of the shooting - I’m still not sure why this was the case.
1) Radically change the way we design new schools, and renovate existing schools.
2) Only have a single point of entry and exit, vestibule entries with automatically locked doors.
3) Security camera coverage of the entire school and exterior grounds, with a full time staff member solely monitoring the cameras.
4) Verification that all classrooms and hallways are properly sprinkled and that the system is fully operational.
5) Every classroom door is replaced with a bullet resistant panel and on mag locks that remain shut and locked at all times.
6) Fire alarms do not automatically override any other security system in place. When's the last time we've had a massive fire break out in a sprinkled school that killed dozens of kids. Sorry Fire Marshall's.
7) 1 armed individual for every 100 students. Plain clothes dressed, and at each school exit point during periods of the day when students would be leaving the school.
8) A national training program, 2 weeks long, administered by the Marshall's program. The program would effectively train individuals, that have shown to be capable with firearms and have passed extensive background checks and mental checks, to become deputized Marshall's that are allowed to carry within ANY state or federal building, or ANY school. They would be limited in that they would have zero arresting powers or law enforcement powers, but would be allowed to carry with the understanding that they are only allowed to use their weapon in the defense of others. The program would be free to the individual, but would becoming deputized would not be a paid position.
We need to make schools the hardest target in the country.
