Whose fault?

[Reel Deal]

From what I understand it is a rule. Now, whether it was written with enough detail to expressly state that the ref has a burden of verifying who actually is calling for the timeout, who knows? But if the ref doesn't verify it, doesn't that mean that the ref will call a T.O. if he hears any voice from the sideline asking for one? I would think it is (or should be) on the ref to verify who is asking for the T.O.

P.S. - Gaffney was bobbling that ball. :P
