There is more here than what is in the title. Please read. I will say that it happens more frequently than we might realize that we can see people who are not stable and it is either ignored or the unstable person is pandered to. Not just with mass shootings.
Evidence of more incompetence and cowardice has been exposed from the Parkland school shooting. Seventeen students and staff were murdered on February 14, 2018, at the Marjory Stoneman Douglas School. I will not name the murderer.
You have probably read and remember the armed school resource officer, Deputy Scot Petterson, failed to confront the killer immediately. He did not run to the sound of the gunfire. Instead, he waited outside the school for others to come. Eventually, there were seven or eight deputies outside the school waiting. Officers from another jurisdiction showed up and immediately entered, but it was too late. All the killing was complete. The murderer had fled the scene.
Wikipedia says the murderer was carrying a “duffle bag” and a backpack. That is incorrect. The murderer was carrying a black rifle case, not a duffle bag.
It is a critical distinction, because Andrew Medina, a school security monitor, recognized the rifle case.
Andrew Medina stated the murderer was carrying a rifle bag, and he recognized it as such. He said this in a recorded interview, under oath, shortly after the shooting.
