Watching past school shooting events, and seeing law enforcement go in these situations blindly, greatly disturbed me.
As a registered security officer of the state of Texas for four years, I came up with a suggestion that will immediately help all public schools, colleges, and universities in the event of an active shooter or terrorist acts.
All police, sheriffs, FBI or governing law enforcement agencies should be issued, and have access to, the external web links to the camera surveillance systems of all such institutions so that they have instant visual access to identify perpetrators, zone in on the shooter's location and see injured staff and students.
Furthermore, all educational institutions should be required to update their surveillance to include the entire perimeter of the campus, every hallway and every classroom.
Galveston College has an electronic lockdown system, and excellent surveillance that can see around the entire city block the campus sits on and inside interior and exterior rooms and hallways. I monitor about 100 views of two campuses; 380-degree surveillance is a must.
