In 2016, American born Afghani Muslim Omar Mateen committed one of the largest mass murders in American history, killing 49 people in a Florida nightclub, and injuring 58. (It was a "gun-free zone".) The MSM and Presidential Candidate Hillary all agreed that Mateen was an American citizen, and therefore there was nothing to be said about Muslim immigration. (Hillary Clinton actually thought she was scoring a point in a debate when she said in the Third Presidential Debate that Omar Mateen “was born in Queens, the same place Donald was born.” The ballot box proved her wrong. )

How Did the Orlando Muslim Terrorist’s Father Get Into U.S.?

As you may have noticed today, after years of ignoring the concept of “citizenism,” the mainstream media has suddenly converted en masse to citizenism of the most fundamentalist kind: the Orlando shooter was a U.S. citizen. What more do you need to know?

But, being a curious sort, I’m wondering how his father, Seddique Mir Mateen, got to the United States from Afghanistan so the terrorist could be born an anchor baby in New York in 1987.

The elder Mateen is reminiscent of Clock Boy’s dad, who was constantly running for president of Sudan while managing a chauffeur business in Texas. Seddique Mir Mateen, a Florida resident, recently announced on TV his candidacy for president of Afghanistan. Early accounts of his YouTube speeches make him sound megalomaniacal. But on the other hand, some of his political accusations, such as that the real bad guys in the region are Pakistan’s ISI, strike me as not wholly delusional. I can’t tell yet whether he was always a complete loon or if at one point he might have seemed to somebody in Washington as the kind of potential Afghan politician it might be handy to have on ice in the U.S. in case of regime change in Kabul, the way lots of members of the Karzai family (that provided the new U.S. backed president of Afghanistan after 9/11) were running restaurants in the U.S. before 9/11.

The younger Mateen referenced the Tsarnaev Brothers of the Boston marathon bombing in his call to 9/11 and had earlier claimed to know them. I’m of course reminded of the unanswered question of how the Tsarnaevs (and their buddy Todashev) got certified as refugees. With the Tsarnaevs, it appears likely that their Uncle Ruslan, a Washington DC area lawyer working on pipeline issues, got some strings pulled, perhaps when he was the son-in-law of CIA legend Graham Fuller and they were working on a Chechen resistance front together. The idea that Uncle Ruslan might one day wind up in an Independent Chechnya as the pro-American Energy Minister seems like a not implausible contingency plan.

But there never seems to be much interest in how these people wound up in the U.S. Apparently, it violates the spirit of the penumbra of the Zeroth Amendment to ask how various no-goodniks got here.

Well, now we're getting the answer, via the trial of Mateen's wife as an accessory:

Via Instapundit, where Glenn Reynolds writes "The mysterious lack of information on the Las Vegas shooter is causing me to wonder if he was some sort of federal informant, too, or if one was sufficiently hooked in that it would be embarrassing to release. We’ll probably find out eventually."

Eventually may be too long. Also, however the father got in, it seems that this "informant" thing may be why the younger Mateen wasn't arrested in 2013—which, as with Nicolas Cruz, might have prevented this crime:

Noor Salman trial: Pulse gunman's father revealed as FBI informant, but judge won't dismiss case

By Gal Tziperman Lotan and Krista Torralva, March 26, 2018

Pulse nightclub gunman Omar Mateen’s father, Seddique Mateen, was an FBI informant for more than a decade before the 2016 mass shooting and is facing a criminal investigation in connection with money transfers to Turkey and Afghanistan, it was revealed on Monday during the trial of Mateen’s widow.

FBI Special Agent Juvenal Martin also testified that he considered developing Omar Mateen as an informant after closing an investigation into comments Mateen made at work in 2013 about belonging to terrorist organizations.[More]
