Actually Paul Perillo was on WEEI today and he had a slightly different version of how the Q & A session came to pass. Apparently after he made his statement he returned to the locker room. Media were in there milling around and leaving him be until they noticed he was doing a one on one with Karen Guregian. Apparently, while the rule is you do not interrupt one on ones out of professional courtesy, competitive jealousies got the better of them and some of them demanded equal access. That led to the impromptu Q & A.
That is all right...when the doors to the locker room first opened, he called over folks for a statement. After that dispersed, he was approached by a camera crew who asked him about his beard. Then Karen approached him, and Paul is right, some people (I suspect I know who it was) don't respect a one-on-one and next thing you know, he was swarmed again and was answering questions.
