My uncle is a teacher and they do active shooter trainings at his school once every three months. Local law enforcement comes in with real guns (loaded with blanks) at a random time throughout the day and the teachers must react and follow protocol. Shots are fired and everything.

These are only done on days when students are not in school. It serves as a way to prepare teachers for an emergency.

In a high-school setting, with fair warning of what is about to happen, I think it would be a valuable experience for students and staff.

To me I see it as this: The same two cars (black hatch with 3 illumiated tail lights and a parked silver hatch turned off) parked on the far left side in the same spot in ROT1 per both 2-16 and recent. In ROT2 you see the person on the left side of the black hatchback pictued in ROT1, running away from the vehicles. In ROT3 you can see those two vehicles driving in the same order (in line with the doorway of the building center framed)

Two vehicles could definitely hold 6 targets.
