Even if it happened, it would take YEARS for "massive and reasoned change" to have any effect while more kids are killed. Shooters go after schools because they are a SOFT target. Protect the grounds now and save lives. Manned security "man traps at all entrances. Hardened classroom doors with remote triggered locks. Teachers and all staff with alarm triggers going to the school and local PD. Train and arm willing staff with monthly training. Make it so someone can't just walk in and start shooting. We protect banks, offices and government buildings with similar methods - WHY NOT SCHOOLS!!!
