Inmate caught with Shank. Probably planted by a Guard.

They can give you up to five more years in prison for possession of a weapon. This is one of the most common tricks for the prison staff to plant these on the Inmates to get them more time. Most likely he is innocent. And even if he is not innocent, it would only be for his self protection because the guards are not able to keep the inmates safe. Either way, it's the fault of the Federal Bureau of prisons.
