> They had access to the school just like everyone else
They literally did not. They had access to the school from a different entrance than everybody else. Specifically, one intended for cargo before people.
That's a different sense of "just like". Not "in the same manner", but "to the same extent".
Would it have been different, if they had everyone take the cargo entrance?
They also literally cannot have the same access like everyone else, since they're in a wheelchair. Everything will be different.
