Only when it's committed in Obama's Amerika. Nidal Hassan, in spite of repeatedly yelling "Allahu Akbar" while gunning down unarmed (don't get me started on this) American soldiers was not commiting jihad, he was stressed out and committed workplace violence.
Syed Rizwan Farook and his Saudi-born bride Tashfeen Malik just "spontaneously" broke due to stress and committed workplace violence yesterday in San Bernardino, CA. Malik was chosen for her devoutness and willingness to wear a hijab (no pictures were available of her face, hmmmm.)
If there is such a thing as "modern" or "moderate" Muslims, that's okay. They're as big a target of jihadis as non-believers are, probably more-so. But I guarantee you, this will not increase the talk of halting Muslim refugees, because hey, it was just more workplace violence.
