How is that so? They wouldn't 'know' that at all. Only one boss of the five families has ever ratted, that obviously being Massino. So to say they would 'know' that another boss is taped up is silly. They may be wary of many things, and it may enter their thoughts, but I don't believe they would not go for that reason alone.

And on top of that, if there were to be a meeting of the top bosses today they would all be patted down and searched more vigorously that normal.
