According to an agency in the U.K., some prisoners over there are utilizing interactive gaming tools to communicate with others on the outside. Bill Hughes of S.O.C.A. (Serious Organized Crime Agency) is quotes as saying this is happening and the Prison Service is concerned. The Prison Service denies same.
Seriously, I can envision a bunch of grown men hunched over consoles behind bars playing "Super Mario" (tm) or some other such game as a means of ordering hits or whatever.
Members of organized crime who are in jails and prisons have always found ways to communicate their directives to those on the outside. Whether it is via ultra-small handwriting in letters or elaborate hand signals, prisoners will continue to create code. I have to hand it to the fellows who figured out how to use gaming consoles to charge minutes to their cell phones-- very creative, guys.
