But we also have to harden access and have enough armed staff, be that specially trained teachers like they have in Argyle Texas, or paid armed officers, there has to be enough armed people that at least one of them can get to every part of the building in 2 minutes or less.

OK, so the Parkland High School. Five acre campus. A dozen buildings. Three thousand students. How many armed guards do you figure they will need?

They need several armed teachers and staff in each building. If they want to have guards rather than allowing their employees to protect the children and themselves they will need to hire enough of them to cover each building properly..
