Right -- If I'm the floor,I ask the dealer whether the cards were mucked. If the dealer can't say he/she thought cards were mucked, I regretfully rule that they were live (unless I can determine otherwise myself from the position of the cards on the table).

Let's change the facts a little -- Villian turns the cards face up and says "I guess you have me." Before anyone says anything or the dealer moves the chips, he says -- "Wait, I have a straight flush, I call" Under these facts, I think its a live hand. The fact that a Jerk spoke up doesn't change this.

So, we need to determine whether the actions constitute a muck, and the dealer is the best person to do this.
