Why is this a repeat scenario, no not mass shootings, we know why those occur, the scenario on the fbi knew all the mass shooters, before they executed their schemes, and took innocent lives, while the fbi makes blanketed statements on how they were watching said suspect, and they were on the radar list, but they as an law enforcement secret service organization, allowed these people to enact the crime, they claim, they the fbi knew,they were capable of committing?
