A report from the Boston Regional Intelligence Center, which receives Department of Homeland Security funding, warned about danger at the finish line of the Boston Marathon prior to the bombings that took place last month.
The 18-page report noted that the finish line was an "area of increased vulnerability." The Los Angeles Times also notes that the report said there was a threat of "small-scale bombings" by extremists.
Despite those warnings, the report concluded that there was "no credible, specific information indicating an imminent threat." Unfortunately, that conclusion proved incorrect.
"The FBI has not identified any specific lone offender or extremist group who pose a threat to the Boston marathon," the report reads.
The FBI has acknowledged that agents had interviewed one of the suspected bombers, Tamerlan Tsarnaev, in 2011. The agency decided that he was not a threat at that time, Newser reported.
During a hearing on Thursday, the House Homeland Security Committee examined what was known by the FBI and other agencies before the Boston bombings. Police officials from Boston said that they were never alerted by the FBI about the presence of Tsarnaev.
"We would have liked to have known," said Boston Police Commissioner Edward Davis. "We would certainly have looked at the information. We would certainly have talked to the individual."
He added: "I can't say I would have come to a different conclusion [than the FBI].”
Richard DesLauriers, special agent in charge of the FBI's Boston office, said that local law enforcement officials had access to information about Tsarnaev. DesLauriers said they could have looked at the Guardian Threat Tracking System to review intelligence data.
"Boston [terrorism task force] members, including representatives from the Boston Police Department , were provided instruction on using Guardian, including suggestions on methods for proactively reviewing and establishing customized searches, which would allow them to be fully informed of all [task force] activity that may affect Boston and the Commonwealth of Massachusetts," DesLauriers said.
