I certainly agree with that, and it was going to be my point, too, to have the witnesses at the beginning of the meeting. Sometimes we have heated discussions. There are many other things. I think it is a matter of order and good process that it be kept to the end of the meeting. I think it could be disruptive.
You're starting a meeting well by having your witnesses properly ushered in and properly seated. From the point of orderly process, I think that should be maintained out of respect for the witnesses, and the discussion, should it ever be a heated discussion, should be in the final 15 minutes.
