The sharks smell blood in the water. The fact that it is another shark that's bleeding is immaterial.
I have witnessed sharks descending on another bloody shark in the water and I'm glad your post reminded me that analogy.
If it's true that 3 of the 4 fired CBS executives plan to file suit over it, that would be a most amusing turn of event. CBS would then be forced to either go through the "discovery process" which would put the lie to the results of their "investigation" or have to negotiate huge settlements to keep it out of court, which, in effect, admits to the cover-up. I guess you could say CBS finds itself "between a Black Rock and a hard place".
If I were one of the executives in question, I'd be happy as a clam knowing that I could squeeze CBS for enough cash to provide for my grandchildrens' grandchildren.
