"Sheriff Joe" as you affectionately call him had his authority to in any way enforce immigration law specifically rescinded by Homeland Security on Dec. 11. 2011.  Nevertheless Arapio continued with his program of detaining Latinos without any ground for charges under his jurisdiction.  Subsequent court orders enforcing this directive were issued -- and consistently ignored --  leading to his conviction of Contempt of Court.

You are aware that being "pardoned" does not make you "not guilty"?  Just not subject to penalty.
