Does Libor Manipulation Deserve The Death Penalty?

Bloomberg's William Cohan released a provocative piece last night, headlined by the even more provocative "UBS Libor Manipulation Deserves the Death Penalty." We can only assume that Cohan is being metaphorical - after all, despite the rare occasional recent criminal charge no one has still gone to prison for the biggest coordinated manipulation of a benchmark fixed income market for years: something previously relegated to the fringes of crackpot conspiracy theories - after all, so many people were in on it, how can they possibly all keep their mouths shut - you know, the usual excuse against massive conspiracy theories, at least until they become conspiracy fact. Yet one wonders: will current and future ongoing market manipulations ever cease when there is no real deterrent: after all spending a few years in jail is certainly worth a few million in ill-gotten proceeds, even assuming the termination of a career in finance. Is Cohan being rhetorical? Or has the time for some true vigilante justice finally come? Because in a world increasingly best portrayed by the 2009 movie "The International" where one has to "go outside" a captured legal system to get real justice, is vigilantism eventually coming to every town near you, once the money illusion ends? And a bigger question - is this the main preemptive reason for the gun control push seen so vividly in recent days and months?

There is no point in mincing words: UBS AG (UBSN), the Swiss global bank, has been disgracing the banking profession for years and needs to be shut down.

... On Dec. 19, the bank paid $1.5 billion to global regulators -- including $700 million paid to the CFTC, the largest fine in the agency’s history -- to settle claims that for six years, the company’s traders and managers, specifically at its Japanese securities subsidiary, manipulated the London interbank offered rate and other borrowing standards.
