Dunno, but there is or certainly should be a presumption that this kind of senseless, unprovoked attack and mass killing are done by a Islamic jihadist.

The link below is a list of 93 deadly Islamic terror attacks made on American soil since 1972 that supports such a presumption.

Most of those weren't mass shootings.

My presumption with these types of mass shooting events is the perp will be an emasculated white loser who was never taught how to deal with life's challenges.

I'm usually right.

In recent history, senseless, unprovoked attacks like this one and these other recent ones are almost always acts of Islamic jihadism.

Until proven otherwise, I presume this was also done by an Islamic jihadist (convert).
