Authorities: San Bernardino Terrorists May Have Been 'Triggered' By Christmas Decorations

Yes, that's what did it.

One year after Syed Farook and Tashfeen Malik carried out their heinous terrorist attack at the Inland Regional Center in San Bernardino, California, ABC's Nightline revealed never-before-seen videos and photos, as well as interviews, with those present during that fateful day. 

Among the revelations in the report is authorities' claim that the attack may have been "triggered" by the fact that Farook was forced to attend a "mandatory employee training session and lunch replete with holiday decorations, including a Christmas tree": 

Emails discovered by the FBI and police reveal Farook’s wife, Pakistani native Tashfeen Malik, objected to the Christmas setting and was upset her husband had to go.

Just before the attack, Farook posed with four fellow county employees in front of a Christmas tree in a conference room.

A short time later, 14 people were killed and 22 others injured when Farook and Malik opened fire at the meeting with assault rifles.

“She had essentially made the statement in an online account that she didn’t think that a Muslim should have to participate in a non-Muslim holiday or event,” said San Bernardino Police Chief Jarrod Burguan in an exclusive interview with ABC News that aired on ABC News’ “Nightline.”

“That really is one of the very, very few pieces of potential evidence that we have that we can truly point to and say, ‘That probably is a motive in this case,’” he said.

Four hours after their rampage, Farook and Malik were shot dead in a gunbattle on a San Bernardino street with police.

Seriously? A Christmas tree triggered a terrorist massacre that resulted in 14 people dead and 22 injured? Why is the simplest answer -- Islam -- never acceptable or enough? For savages like Farook and Malik, anything anathema to their Islamic worldview -- which is to say everything about our freedom-loving Western society -- would be "triggering." This is why they are here: to inflict their Islamic worldview on American society and punish non-believers. 

We also know that Farook and Malik had been plotting their attack long before encountering any off-putting tinsel or mistletoe.  

The very same ABC News report provides footage of Farook two days before the attack practicing at a local firing range: 

The video shows Farook adjusting the sights on his rifle and then firing at paper torso silhouette targets, one of which was later recovered in the shooters’ vehicle and led authorities to the range.

“They had high-powered weaponry. They had lots of ammunition. They had bombs at their disposal,” said Burguan.

"It certainly surprised me that you’d have a woman with a 6-month-old baby who’d do something like this," David Bowdich, who led the FBI's Los Angeles office at the time, told ABC. "That’s very hard for us to comprehend."

That is because they don't understand Islam, where the truly devout have no regard for the sanctity of life: not their own, not even that of their children.
