Ensuring that U.S. Students are Safe in Classrooms

Silent panic alarms in all classrooms in all schools that notify law enforcement of a need of their presence at the school. Electronic locking doors that don't accept usual access credentials during a lockdown, i.e. student/teacher access codes disabled, requires law enforcement to unlock the system in event of a shooting. Sensors to detect the presence of any dangers towards students using satellite systems, prior to the dangers arriving at any school, to alert law enforcement of any violations of any restraining orders against weapons in or around schools, such as by any travelers or passerby’s, including correlations to any past criminal offenses, including intelligence crimes.
