It's good to document this stuff but I find that this enquiry is slightly misaligned in that they keep asking leading questions to people they don't like and not letting them ramble or even talk too quickly.

Getting everyone in the same chair is very expensive politically, get the most from it.

Cummings in particular I think was asked a lot of questions that I found unreasonable. Maybe he deserves it, who knows, but he thinks on a different level than anyone else they're going to hear from — there are loads of scientists, but that's not his schtick.
