Unfortunately, we'll likely never know if it was terrorism. Public policy is not to use the "term" as it may "paint" the wrong picture. We have to be politically correct yuh know.
For now, I'm inclined to believe that these two just didn't like the fact that it was a bar OR they just wanted to see how a "gun" works. I doubt if it was a targeted shooting as the video indicates, no time was taken before the guy started shooting, unless, of course, it was the bar itself that was the target. It could be any one or more of these reasons. It'll be interesting if we actually ever find out.
Never did hear this on the news I listened to on the radio, so obviously, when it comes to "Mohammad's" there's selective reporting.
