>>>> What makes you think the NSA's ineffectual dragnet would suddenly have been super effective if they had done "profiling"? Because all of the warning signs were there in every case and and were still blatantly overlooked. For example, in the Hasan case: "Intelligence agencies learned that Hasan had contacts with an Islamist sympathetic to al Qaeda and relayed the information to law enforcement, but no action was taken, the report noted." "The report said evidence of Hasan's "radicalization to violent Islamist extremism" was on display to his colleagues during his military medical training and he was referred to as a "ticking time bomb" by two of them." For example in the Boston Bombings: "Federal Bureau of Investigation officials ignored warnings about the radical origins and nature of the mosque frequented by the Tsarnaev brothers for years before this April’s deadly Boston Marathon bombings." "After tough questioning by the highly perturbed Texas Republican Rep. Louie Gohmert, Mueller confessed that he had absolutely no idea the Tsarnaevs’ mosque was founded by Abdulrahman Alamoudi, who was convicted in 2004 of plotting with Libyan dictator Muammar Gaddafi to assassinate Saudi Crown Prince Abdullah Bin Abdul-Aziz." In the case of Richard Reid, had he not been so inept, he would have been successful, and yes there were warning signs there too: "The Government ignored specific warnings more than a year ago that Muslim extremists were infiltrating prisons and recruiting inmates, The Telegraph can reveal. Jack Straw, the then Home Secretary, and Martin Narey, the director general of the Prison Service, were told by mainstream Muslim leaders that "bad practices" meant that untrained, radical imams could operate in prisons." Richard Reid was recruited in jail, then sent to Pakistan and Afghanistan to train with Al Qaeda. He was also a member of a very radical mosque in North London. As for the Holmes, Alexis and Lanza, you make a good point, but they could've been stopped had there been proper mental health resources in place to help these people. Holmes had clear mental health issues that have been well documented throughout his case. Alexis thought he was being controlled by ultra low frequency radio waves and the government was trying to control his mind. Lanza was said to have a personality disorder and had trouble socializing and didn't have any friends in school. You can blame the Lanza shooting on his mother for not keeping her guys locked up and controlled properly so they would be out of reach of her son.
