Why Omar Mateen’s obvious danger signs were missed and he was allowed to purchase weapons

We know Orlando jihad terrorist Omar Mateen worked for a DHS contractor the people supposed to guard our airports, federal buildings, and nuclear facilities.  We know that in 2013 and 2014, his co-workers reported to his employer that he was acting weird, and he was reported to the FBI and watched for a while.  Why wasn't he fired?

Probably because the employer had a diversity requirement imposed by the DHS and because CAIR, et al. were sure to finance a lawsuit against them even if DHS didn't hold them to strict account for such a firing.

Of course the FBI agents, probably like the Ft. Hood shooters' military co-workers, had to fear reprisals if they acted on their suspicions and stripped away his gun privileges.  But the media and the government will, I predict, be all too happy to blame the contractor for the government’s failures.

Thomas Lifson adds:

Keep in mind the systematic purge from counter-terrorism training of any references to Islam.  This may well be why the FBI investigations were closed, and Mateen was free to purchase his arsenal.

Patrick Poole has covered this topic extensively:

In what some experts have termed a hostile “political warfare campaign” driven by an alliance between the administration, Islamic organizations and cooperating media figures, analysts and subject matter experts were blacklisted, and books and training materials were purged from official counter-terrorism training programs government-wide.

This “purge” has contributed to clues being missed by the FBI in major terrorism cases, including…bombing of the Boston Marathon
