Is the Problem with Finger-Pointing That We're Using the Wrong Finger?

Help me. I'm confused. Are we supposed to ignore the past, forget finger-pointing and blame-gaming and look forward? Or are we supposed to demand accountability? Or some third option?

On the one hand, we have the expectations of a lot of Obama Nation for something between John Conyers' Truth and Reconciliation Commission and a post-mortem impeachment of Bush, Cheney, et al. On the other, we have Obama's anodyne reassurances about looking to the future, mirroring the Bush insistence that an "accountability moment" happened, in November 2004, and is now past history.

On the one hand, we have the current Administration's embrace of waterboarding, extraordinary rendition, warrantless wiretapping. On the other, we have Tim Geithner's apparently innocent failure to pay some taxes in a timely manner.

Hey, I bow to no one in my scorn for a Treasury Secretary-designate who can't figure out his taxes, but -- are the same senators who pooh-pooh any idea of (to use a Clinton impeachment era phrase) sending a message to our children about federal officials flouting the law going to get all pious about Geithner's boo-boo? And is the only reason because Geithner isn't yet sworn in?

What's the part of this I'm missing? You can violate the Constitution and our treaty obligations (which the Constitution makes part of the law of the land) with impunity, but woe unto you if you run afoul of the tax laws?
