No Metal Detectors at the Scrool?
Probably not.
I doubt they even have a fence..................
First of all where ws security in the school?
Was a drill alarm set first and did he go in school then?
Then after all went back inside, he waited until all was settled down.
Then he pulled the alarm the second time, and began shooting when the students started exiting class rooms.
Was all the entrances secured locked with security cameras at each door.
The officials are not telling how the perp gained entrance to the school.
The staff watched him get out of the Uber and walk into the school but did nothing because they had no weapons.
