The wife of British aid worker Alan Henning, who is being held by ISIS, released a statement on Tuesday in an attempt to appeal to the terrorists' internal sense of justice. "I have been told that he has been to a Sharia Court and found innocent of being a spy and declared to be no threat. I implore Islamic State to abide by the decisions of their own justice system," Barbara Henning said. This is the second video where Barbara has pleaded for her husband's release.
