But surely if the police have requested your presence at a reconstruction then the fund would have covered that. As far as I recall it paid for some repayments on the McCann mortgage (im sure there was something about that)- and there was a hoo haa at the time.

That was only stopped after they became formal suspects. None of the Tapas 7 were formal suspects - so Im sure it would have been ok.
