'Wrong decision' not to go in during shooting - Texas official

STORY: "With the benefit of hindsight where I'm sitting now, of course it was not the right decision, it was the wrong decision, period. There's no no excuse for that," McCraw said at a press conference.

Panicked children and teachers placed half a dozen calls to 911 emergency services from the Texas classrooms where a massacre was unfolding, pleading for police to intervene, while 19 officers waited in a hallway for nearly an hour before entering the room, McCraw said.
