Last night we watched the always depressing Bill Moyers, where he interviews William Black, who led the S&L and Keating Five investigations. Black described the Obama administration's complete failure, and more importantly, lack of interest, in prosecuting banks that caused our current crisis (link, including summary, transcript, and video).

And then as if on cue, this news this morning:

The Justice Department is preparing a fresh round of attacks on the world's biggest banks, again questioning Wall Street's role in a broad array of financial markets.

...

The charges will most likely focus on traders and their bosses rather than chief executives. As a result, critics of the Justice Department might view the cases as little more than an exercise in public relations, a final push to shape the legacy of Attorney General Eric H. Holder Jr., who was blamed for a lack of criminal cases against Wall Street executives.

Yet the breadth of the suspected wrongdoing in the currency inquiry -- Deutsche Bank, Citigroup, JPMorgan Chase, Barclays and UBS are among the dozen or so banks under investigation -- might distinguish it from the piecemeal nature of the crisis-era investigations.

And prosecutors are testing a new negotiating tactic, two lawyers said, using the currency investigation as a cudgel to potentially reopen other cases. Arguing that the misconduct would violate earlier settlements involving interest rate manipulation, prosecutors have threatened to impose new penalties in the interest rate cases.

We shall see. I am sure Min will say i'm Charlie Brown running up to kick Lucy's football again. But maybe with both Holder and Obama thinking about their legacy, we'll see something more than trivial fines this time.

Update: here's the Matthew Yglesias explainer on this.
