Orlando shooter was a fan of Fort Hood shooter's mass murders

In 2013, Mateen, then 26, was working as a private security guard for G4S Secure Solutions USA, Inc. at the St. Lucie County Courthouse in Fort Pierce. The Sheriff's Office is responsible for hiring the company to provide security at the courthouse.

The sheriff first became concerned about Mateen when it was rumored that he voiced derogatory comments to his co-workers at G4S, the sheriff said.

"We could never substantiate those claims," Mascara said. "However, shortly after that rumor, (Mateen) made an offensive comment to one of my employees at the courthouse."

Mateen made many inflammatory comments at the courthouse in 2013, including a statement that Fort Hood, Texas, shooter Nidal Hasan was justified in fatally shooting 13 people and injuring more than 30 others in 2009, Mascara said Wednesday.

That mass shooting took place Nov. 5, 2009. Hasan was an Army major and psychiatrist. Soon after the attack, it was reported that his colleagues were aware that Hasan had been increasingly radicalized for several years.

In addition to commenting about Fort Hood, Mateen made derogatory remarks about women and Jews, the sheriff said.

"That sent red flags to my staff and me and the FBI was immediately notified," he said.

The FBI investigated Mateen, but could not conclude he had leanings toward terrorism.

Wait a minute.  The guy said that the mass murder of soldiers at Fort Hood was justified and the FBI could not conclude he had leaning toward terrorism?  I find that remarkable.  His employer should have told him if that was his attitude then he was not cut out for a job as a security guard.  It should have also earned him a permanent spot of the terrorist watch list.
