Bad devoids who look human but are not will kill when they set out to most of the time. They have the element of surprise.
Locking and hardening the schools is good but there are 500,000 school busses that transport over 25 million kids a day. These are the very soft targets.

School buses are not soft targets for mass shooters. Shooting from the outside is difficult. Forced entry is not easy. Drivers are taught to turn off their engines and throw the keys out of the window. If a shooter begins with shooting the driver, who will control the bus? In an attempted forced entry the driver will try to close the door and may pull away. If the bus is moving and the driver becomes disabled, the hijacker is in a terrible predicament. (However, students are taught every year how to stop a moving bus if the driver were to pass out. You just pull the emergency brake, which is accessible from the aisle.)
Terrorist might target school buses, but that’s a different issue.
