The most bizarre story of the weekend was that of Bank of America's 29-year-old banker Rurik Jutting, who shortly after allegedly killing two prostitutes (and stuffing one in a suitcase), called the cops on himself and effectively admitted to the crime having left a quite clear autoreply email message, namely "For urgent enquiries, or indeed any enquiries, please contact someone who is not an insane psychopath. For escalation please contact God, though suspect the devil will have custody. [Last line only really worked if I had followed through..]”

But while his attempt to imitate Patrick Bateman did not go unnoticed, even if it will be promptly forgotten until the next grotesquely insane banker shocks the world for another 15 minutes, the question that has remained unanswered is what did young Master Jutting do when not chopping women up.

The answer, as the WSJ has revealed, is just as unsavory: "he had been part of a Bank of America team that specialized in tax-minimization trades that are under scrutiny from prosecutors, regulators, tax collectors and the bank’s own compliance department, according to people familiar with the matter and documents reviewed by The Wall Street Journal."

Basically, when not acting as a homicidal psychopath, Jutting was facilitating full-blown tax evasion, just the activity that every developed, and thus broke, government around the globe is desperately cracking down on, and why every single Swiss bank is non-grata in the US and may be arrested immediately upon arrival on US soil.

More from the WSJ:

Mr. Jutting, a U.K. native and a competitive poker player, worked in Bank of America Merrill Lynch’s Structured Equity Finance and Trading group, first in London and then in Hong Kong, according to these people and regulatory filings. Mr. Jutting resigned from the bank sometime before Oct. 27, which police say was the date of the first murder, according to a person familiar with the matter. The trading group, known as SEFT, employs about three dozen people globally, one of these people said. It helps hedge funds and other clients manage their stock portfolios, often through the use of derivatives, according to the people and internal bank documents. Mr. Jutting joined Bank of America in 2010 and worked three years in its London office, the bank’s hub for dividend-arbitrage trades, the people familiar with the matter say. He moved to Bank of America’s Hong Kong office in July 2013.

Ironic, because it was just this summer that a Congressional panel headed by Carl Levin was tearing foreign banks Deutsche Bank and Barclays a new one for providing structures such as MAPS and COLT, which did precisely this: give clients a derivative-based means of avoiding taxation (as described in "How Rentec Made More Than 34 Billion In Profits Since 1998 "Fictional Derivatives").

As it turns out not only did a US-based bank - Bank of America - have an entire group dedicated to precisely the same type of hedge fund, and other Ultra High Net Worth, clients tax evasion advice, but it also housed a homicidal psychopath.

Perhaps if instead Levin had been grandstanding and seeking to punish foreign banks, he had cracked down on everyone who was providing this service, Jutting's group would have been disbanded long ago, and two innocent lives could have been saved, instead allowing the alleged cocaine-snorting murderer to engage in far more wholesome, banker-approrpriate activities:

During his time in Asia, Mr. Jutting’s pastimes apparently included gambling. In a Sept. 14 Facebook post, he boasted of winning thousands of dollars playing poker at a tournament in the Philippines. He signed off the post: “God I love Manila.” The comment drew eight “likes.”

Alas one will never know "what if."

But we are certain that with none other than America's most prominent bank, the one carrying its name, has now been busted for aiding and abetting hedge fund tax evasion around the globe, it will get the same treatment as evil foreign banks Barclays and Deutsche Bank, right Carl Levin?
