The cop standing on the right (south?) side of the hallway, looking at his phone was the husband of one of the teachers murdered in that room. The story goes that he was detained and is gun taken away trying to get to his wife. Seems to me like he let her die in there. Lack of training is one thing, but the cowardice on display here astounding. I feel like these children would have been better served by a handful of average Joe’s off the street.
