Not the first time at all. Wasn’t the parkland shooter on the FBI radar. Cops had been to his house many times for issues. Then I believe there was another they caught trying to flee with the rest of the students. I know they have thousands of things come into the office every day.
The Parkland kid was a result of formal Leftist policy put in place by the sheriff’s department and school system that resulted in minorities being ignored for egregious behavior, because of racism. So the policy was spread nationally by the Obama Administration. Of course. And is still in place in many locales.
Go read the book Why Meadow Died for details. Heavily footnoted, co-written by Meadow’s father.
And the San Bernardo shooter and wife were highly suspect, due to the social media data mining from the work by Phil Haney, which he was ordered to purge.
