One of the side-missions in Arkham Origins is called "Blackgate Prisoners," and unlike the others, is not centered on a super-villain, but multiple convicts. The one shown in the picture is not an especially familiar face, but might there be a way to ascertain his identity?
That booking number, for example - to whom does it belong?
The answer may surprise you...
It's O.J. Simpson.
Many thanks to my Argentinean tipster "Morton" for bringing this to my attention.
