THE FBI HAS CONSISTENTLY UNDERPERFORMED FOR THE ENTIRE 21ST CENTURY: Howie Carr: FBI whiffs again on Colorado mass shooting suspect.

So now it turns out that the FBI knew all about the accused Boulder shooter, but paid no attention to the obvious warning signs until police say the rabidly anti-American immigrant from Syria murdered 10 U.S. citizens in the supermarket.

“The suspect’s identity,” the New York Times reported, “was known to the FBI because he was linked to another individual under investigation by the bureau, according to law enforcement officials.”

Stop me if you’ve heard this one before.

The Famous But Incompetent FBI likewise knew all about accused shooter Ahmad al-Aliwi Alissa’s fellow Muslim immigrants who committed mass murder, like the Tsarnaev brothers — but did nothing until those welfare-collecting “asylees” blew up the Boston Marathon.

The FBI also had early warnings about the Muslim terrorists who shot up the gay nightclub in Orlando, the Christmas party in San Bernardino, Fort Hood, the cartoon-drawing contest in Texas … and yet the G-men sat on their soft hands until scores of Americans were murdered in cold blood.

But it’s not only foreign Muslim terrorists the FBI can’t be bothered lugging. It’s domestic killers as well.

For instance, in 2018 the FBI’s national tip line got a 13-minute-long earful from the aunt of the Parkland High shooter Nikolas Cruz — but did nothing until 17 people were gunned down.

Remember serial killer Gary Sampson? Before he murdered three innocent men in 2001, he called the FBI office in Boston from a pay phone in Abington and offered to turn himself in on some unsolved bank robberies.

But it was a Friday afternoon, so the FBI “disconnected” his call and didn’t bother to pick him up. The next day, Sampson started his two-state carjacking murder spree.

It’s not an impressive track record.

9/11 Flashback: “Though not really funny, there’s a certain Keystone Kops angle to the Moussaoui investigation, too, as Congressional investigators have discovered. FBI investigators misunderstood the law, and were thus too slow to search Moussaoui even though the evidence in their possession was more than sufficient. The bureaucratic resistance to searching Moussaoui was so great that field agents in Minnesota wondered — before Sept. 11 — if Usama bin Laden had a mole in Bureau headquarters.”

There’s a quiet scandal at the heart of Sept. 11; one that for different reasons neither the government nor the privacy lobby really wants to talk about. It’s this: For two and a half weeks before the attacks, the U.S. government knew the names of two hijackers. It knew they were al-Qaida killers and that they were already in the United States. In fact, the two were living openly under their own names, Khalid al-Mihdhar and Nawaf al-Hazmi. They used those names for financial transactions, flight school, to earn frequent flier miles, and to procure a California identity card.

Despite this paper trail, and despite having two and a half weeks to follow the scent, the FBI couldn’t locate either man—at least not until Sept. 11, when they flew American Airlines Flight 77 into the Pentagon.

Too busy playing politics, then and now.
