Lets see the link/source which substantiates this.
I'd really like to see it.
It doesn't substantiate or prove it, but it clearly isn't wild and unfounded either. I believe that the speculation is based on this:
Bill Warner, Sarasota private investigator: James Holmes, DOB 12/13/1987, the car he was driving had Tenn license plates. The Batman movie portrays the OWS crowd in a negative vein,the new Batman movie featured the villain as an Occupy Wall Street type. I would first look at the possibility that James Holmes, DOB 12/13/1987, was caught up in the OWS movement took it upon himself to strike back against THE MAN.
