Top Texas law enforcement official says 'wrong decision' to wait to get mass shooter inside school

A top Texas Department of Public Safety official on Friday acknowledged that officers waiting too long to go into the elementary school earlier and stop the mass shooter who had barricaded himself inside a classroom was "the wrong decision."

The acknowledgement was made by the agency's Col. Steven McCraw when taking question during a press conference updating the situation.

He said the incident commander's "thought process" was "this was a barricaded subject situation." 

"Where I'm sitting now, of course it was not the right decision," Craw said. "It was the wrong decision, period. There's no excuse for that. But again, I wasn't there." 

He also said the the school district's chief of police was the commander.
