The banks' laundering transactions were so brazen that the NSA probably could have spotted them from space. Breuer admitted that drug dealers would sometimes come to HSBC's Mexican branches and "deposit hundreds of thousands of dollars in cash, in a single day, into a single account, using boxes designed to fit the precise dimensions of the teller windows."

This bears repeating: in order to more efficiently move as much illegal money as possible into the "legitimate" banking institution HSBC, drug dealers specifically designed boxes to fit through the bank's teller windows. Tony Montana's henchmen marching dufflebags of cash into the fictional "American City Bank" in Miami was actually more subtle than what the cartels were doing when they washed their cash through one of Britain's most storied financial institutions.

Though this was not stated explicitly, the government's rationale in not pursuing criminal prosecutions against the bank was apparently rooted in concerns that putting executives from a "systemically important institution" in jail for drug laundering would threaten the stability of the financial system. The New York Times put it this way:

Federal and state authorities have chosen not to indict HSBC, the London-based bank, on charges of vast and prolonged money laundering, for fear that criminal prosecution would topple the bank and, in the process, endanger the financial system.

... the reasoning here is beyond flawed. When you decide not to prosecute bankers for billion-dollar crimes connected to drug-dealing and terrorism (some of HSBC's Saudi and Bangladeshi clients had terrorist ties, according to a Senate investigation), it doesn't protect the banking system, it does exactly the opposite. It terrifies investors and depositors everywhere, leaving them with the clear impression that even the most "reputable" banks may in fact be captured institutions whose senior executives are in the employ of ... murderers and terrorists. Even more shocking, the Justice Department's response to learning about all of this was to do exactly the same thing that the HSBC executives did in the first place to get themselves in trouble – they took money to look the other way.

And not only did they sell out to drug dealers, they sold out cheap. You'll hear bragging this week by the Obama administration that they wrested a record penalty from HSBC, but it's a joke. Some of the penalties involved will literally make you laugh out loud. This is from Breuer's announcement:

As a result of the government's investigation, HSBC has ... "clawed back" deferred compensation bonuses given to some of its most senior U.S. anti-money laundering and compliance officers, and agreed to partially defer bonus compensation for its most senior officials during the five-year period of the deferred prosecution agreement.

... So the executives who spent a decade laundering billions of dollars will have to partially defer their bonuses during the five-year deferred prosecution agreement? ... That's the punishment? The government's negotiators couldn't hold firm on forcing HSBC officials to completely wait to receive their ill-gotten bonuses? They had to settle on making them "partially" wait? ... What was the Justice Department's opening offer - asking executives to restrict their Caribbean vacation time to nine weeks a year?

So you might ask, what's the appropriate financial penalty for a bank in HSBC's position? Exactly how much money should one extract from a firm that has been shamelessly profiting from business with criminals for years and years? ...

How about all of it ? How about every last dollar the bank has made since it started its illegal activity? How about you dive into every bank account of every single executive involved in this mess and take every last bonus dollar they've ever earned? Then take their houses, their cars, the paintings they bought at Sotheby's auctions, the clothes in their closets, the loose change in the jars on their kitchen counters, ... . Take it all and don't think twice. And then throw them in jail.

Sound harsh? It does, doesn't it? The only problem is, that's exactly what the government does just about every day to ordinary people involved in ordinary drug cases.
...
... There is no reason why the Justice Department couldn't have snatched up everybody at HSBC involved with the trafficking, prosecuted them criminally, and worked with banking regulators to make sure that the bank survived the transition to new management. As it is, HSBC has had to replace virtually all of its senior management. The guilty parties were apparently not so important to the stability of the world economy that they all had to be left at their desks.

So there is absolutely no reason they couldn't all face criminal penalties. That they are not being prosecuted is cowardice and pure corruption, nothing else. And by approving this settlement, Breuer removed the government's moral authority to prosecute anyone for any other drug offense. Not that most people didn't already know that the drug war is a joke, but this makes it official.
