Unfortunately the Trust ends up with a disjointed message, and a disjointed presentation of its message.
What the disjointed nature gives is indeed a signal that both sides should talk... but only after sticking the boot in. It appears to want to be slectively objective, IMHO, have its cake and eat it.
And the switch in tone and direction dilutes the main message.
(Incidentally, I'd be saying this even if you wanted the main message as SISU OUT at all costs - it doesn't alter the fact that the message from the trust is badly disjointed)
That doesn't mean that there isn't a place for questioning (the pdf of questions for SISU for example, very good - although still waiting for the ACL equivalent one that was promised

) but the savage swings in tone make it very hard for the trust to show an identity and what it stands for.
As an aside, the danger of having a public face makes it a focus on the individual and not an insitution. I'm sure you remember the brand new dawn that was hailed when McGinnity replaced Richardson, when Robinson replaced McGinnity... forget the fact the same parties were still there, the public face meant they could get away with a lot in a nice fresh honeymoon period. We've had similar with SISU, with Ranson being replaced (OK, no honeymopon there!) but Dulieu to Fisher showed a state of grace, because the focus was onthe individual rather than the content. So personally I wouldn't be trying to unmask people as it detracts from the issues at heart, reduces it to cartoonesque status.
