Dr. Bennett, I'm going to ask you to please be respectful of all witnesses.
I read a statement here before committee for a reason this morning.
Mr. Tilson, I'm going to bring you to order, please.
I ask that everybody listen very carefully to every single witness in a respectful manner. We're all grownups here, and I think we can do that.
Thank you, Dr. Mangham, and all the rest of the people who are here.
We will now go to Dr. Kerr.
