Orlando Terrorist Omar Mateen was a licensed and armed security guard for a multinational security company that had the Department of Homeland Security contracts to transport illegal alien caught by US Border Patrol agents.

Mateen is still licensed as a weapons eligible security guard through the Jupiter, Fla headquartered US subsidiary of G4S plc, a multinational British corporation that is the largest security provider in the world, according to the Palm Beach Post.

The Bureau of Alcohol, Tobacco, Firearms and Explosives confirmed that Mateen legally purchased 2 firearms — a handgun and a long gun, “within the past few days.”

The Hill reported that Mateen became known to the FBI in 2013 after he made “inflammatory comments to coworkers alleging possible terrorist ties” to other workers at G4S plc, where he was employed since 2007.

Mateen’s first Facebook entry is a December 2011 post by Moner Abu-Salha of a video of Imam calling for death of homosexuals, according to the Palm Beach Post blog.

The FBI investigated Mateen after Abu-Salha in 2015 became the first American suicide bomber in Syria. Omar Mateen lived only 30 minutes south of Abu-Salha’s home in Vero Beach, Fla.

Abu-Salha is known to have traveled to the Middle East, trained, and returned to the Vero Beach and Fort Pierce areas to supposedly recruit Jihadist followers. The FBI has previously said that Abu-Salha did not recruit anyone, but Mateen has an apartment in Fort Piece.

Although Mateen was interviewed by the FBI at least 3 times and was for some period of time on the terrorist watch list, it appears that his security clearances and weapons permits were never suspended.

Breitbart News reported last month that Brandon Judd, President of the National Border Patrol Council, told the Senate Judiciary Subcommittee on Immigration and the National Interest that, “We’re releasing basically everybody as long as you’re not from the country of Mexico.

Border patrol sources told Judicial Watch investigators that the Department of Homeland Security had contracted with G4S to move illegal aliens apprehended at the border inland by vans. According to Judicial Watch, the “detainees,” were then released them into the United States without proper processing or issuing court appearance documents.

G4S issued a statement, “We are shocked and saddened by the tragic event that occurred at the Orlando nightclub. We can confirm that Omar Mateen had been employed with G4S since September 10, 2007. We are cooperating fully with all law enforcement authorities, including the FBI, as they conduct their investigation. Our thoughts and prayers are with all of the friends, families and people affected by this unspeakable tragedy.”

The firm’s website states that the company is the largest security company in the United States and the world. They have operations in more than 100 countries with 610,000 employees. In the US, G4S has more than 50,000 employees.
