Some people say Peter may have chicked out this time, cancelling the debate only after Zodiak had already scheduled the program.  One thing for certain if Peter cancelled the debate because he was afraid of some tough questions, then there is no hope for DPP in 2014. But for benefit of the doubt lets just say maybe Peter knew that he is currently on bail and anything he says or do could be understood the wrong way, which could essentially hurt his freedom.  Smart move Peter.
