CNN reports.

School resource officer Scot Peterson never went in, despite taking a position on the west side of Building 12, where most of the carnage happened, Broward County Sheriff Scott Israel said Thursday.

"I think he remained outside for upwards of four minutes," Israel said Thursday in a news conference. The shooting, he said, lasted six minutes....

President Donald Trump made his first remarks about Peterson while departing the White House on Friday, saying the deputy "certainly did a poor job."

"He trained his whole life," Trump said. "But when it came time to get in there and do something, he didn't have the courage or something happened. But he certainly did a poor job, there's no question about that."

Did he train his whole life for this situation, to go in single-handedly and stop an active shooter, somewhere in a building amid many other people? Or are we really just thinking, how could he not go in and die trying rather than to stay alive only to be mired in hopeless shame?

Moving away from the pitiful figure of Scot Peterson, I want to know how much you think school security guards are going to help. Is Peterson the outlier, or should we expect all the guards we hire to turn out to be a Scot Peterson when the crisis hits?
