LOL... Most of us don't need any more information.... Muslim... Mass murdering people in cold blood.... uhm, TERRORISM! I'm not sure what other sort of 'evidence' you would need, and I wish you would clarify this for me. Are there somehow 'acceptable' non-terrorist incidents where Muslims kill innocent people in cold blood? If so, I am not aware of them... so yes, this WAS an act of terrorism by a radial extremist Muslim, and in 100% of the cases where any Muslim kills innocent people in cold blood, it is safe to conclude it IS an act of terrorism, because there is no other justification for such acts.
I am bright enough to figure that out.
If it was a Christian, or another faith...would that have immediately been "terrorism" your mind?
