Barricaded vs. pinned down

In his account Wednesday, McCraw said that police officers began to “engage” the attacker while he was inside the classroom. McCraw said law enforcement “continued to keep him pinned down in that location” until a tactical team could be put together to breach the classroom.

Also on Wednesday, Olivarez, the DPS spokesman, told CNN that officers responding to the gunman once he was inside “were at a disadvantage because the gunman was able to make entry into a classroom, barricade himself inside that classroom,” suggesting that instead of keeping him pinned in one place intentionally, authorities were unable to get to him.

Speaking on Thursday, Escalon also said the gunman was inside for about an hour before law enforcement officials confronted him.
