Alan Henning travelled to Syria with his muslim 'friends' to help deliver aid to muslims. How naïve was he to think that he can operate in this area and not set himself up as the next victim or at least be in danger? The muslims he was working with were released unharmed. So much for helping followers of The R O P.
There is a distinct possibility that his muslim 'friends' persuaded him to go there so that he could be captured and later beheaded.
They could certainly have been complicit in this and then, of course, cry crocodile tears in order to 'prove' they were not involved.
