LOL - that would be super tenuous! Hopefully we'll get more from them on the record. I expect that they'll just try to be utterly evasive in the expectation that no-one with power will care, and those who do pay attention couldn't think less of them anyway.
It does look pretty dodgy though when questions of Bristol University having ethical permission to carry out a trial rather than investigating they put pressure on the institution that the journalist who raised the questions comes from to shut him up. It fails the headline test which is a good way to judge ethics (i.e. if you wouldn't be able to defend the actions if they were represented in a headline don't do them).
