the wrong decision. not my words but the description from the director of public safety. he said the officers responding made a serious mistake and not immediately going into the classroom where a gunman killed 19 kids and two teachers tuesday. this is coming after extraordinary briefing that provided more clarity about the time line but raised a lot more questions, many more questions. we learned teacher propped open the door. the killer would later enter. the school safety officer responded to the scene and drove right past it as the gunman hid in the school parking lot. they said this was a barricade subject situation and somehow didn t think children were at risk. made that assessment. we learned two students called 911 basically begging for help. they both survived. why did that teacher prop the door open? why wasn t an armed safety officer on school grounds. why didn t the responding officer, there were 19 of them in the school at one point jump into active shooter trai
