That seems more like a lone nutter than anything to do with ISIS. Thankfully all the victims are injured rather than dead, and the culprit is safely under arrest. That doesn't seem like its in the same category as what happened in Paris or the attack we're discussing on this thread.
I agree... someone wanting 5 minutes of fame... needs a Psych evaluation n a stay in an institution.
But still people we don't need on the street to add to an already over burdoned LE.
