The Obama government has rationalised its failure to prosecute anyone (literally, anyone at all) for bubble-related crimes by saying that while much of Wall Street’s behaviour was unwise or unethical, it wasn’t illegal. With apologies for my vulgarity, this is complete horseshit.
When the government is really serious about something – preventing another 9/11, or pursuing major organised crime figures – it has many tools at its disposal and often uses them. There are wiretaps and electronic eavesdropping. There are undercover agents who pretend to be criminals in order to entrap their targets. There are National Security Letters, an aggressive form of administrative subpoena that allows US authorities to secretly obtain almost any electronic record – complete with a gag order making it illegal for the target of the subpoena to tell anyone about it. There are special prosecutors, task forces and grand juries. When Patty Hearst was kidnapped in 1974, the FBI assigned hundreds of agents to the case.
In organised crime investigations, the FBI and government prosecutors often start at the bottom in order to get to the top. They use the well-established technique of nailing lower-level people and then offering them a deal if they inform on and/or testify about their superiors – whereupon the FBI nails their superiors, and does the same thing to them, until climbing to the top of the tree. There is also the technique of nailing people for what can be proven against them, even if it’s not the main offence. Al Capone was never convicted of bootlegging, large-scale corruption or murder; he was convicted of tax evasion.
No need to apologize, it is horseshit. Robbing a bank is a federal offense for which jail time is the rule not the exception. Being robbed by banks, however, seems to be business as usual.
