The terrorist attack in San Bernardino, Calif. that left 14 people dead and nearly two dozen more injured happened one year ago. ABC World News examined what might have “triggered” the attack (brace yourselves):

Via ABC News:

Authorities believe the terrorist attack on Dec. 2, 2015, in San Bernardino may have been triggered by a mandatory employee training session and lunch replete with holiday decorations, including a Christmas tree, that shooter Syed Farook was forced to attend.

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.

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

Well, that’s one way to frame it.

Apparently so, but the reality is:

It must not be politically-correct enough to put it that way.
