Revelations that the FBI had been warned about Florida high school shooter Nikolaus Cruz fit an all-too-familiar pattern, in which apparent law enforcement errors have preceded mass murders.
The FBI was warned about Cruz after he posted on YouTube saying he was going to become a “professional school shooter.” The agency said they couldn’t identify the user who made the threat, despite Cruz posting under his own name. Five months later, Cruz pulled the fire alarm at Marjory Stoneman Douglas High School and began shooting his former classmates with his AR-15.
Other mass shooters and terrorists were similarly on the FBI’s radar — or should have been — before they carried out their deadly attacks.
Dylann Roof, who in 2015 shot nine people at a black church in Charleston, was allowed to purchase his weapon in part because of errors by FBI agentsduring the background check process, the agency said.
