It is not vindictive or resentful to demand that the crimes perpetrated by the Bush Administration be punished.  It must become abundantly clear, through the use of non-partisan judicial means that these were indeed crimes, and that the guilty, no matter how powerful or rich, must be punished for them.

To omit this crucial step towards reforming our nation leaves the very real possibility that the same crowd of henchmen will rise again the moment Obama stumbles (which everyone invariably does at one point or another.)  Had the Reagan crowd been put in prison for Iran/Contra by Clinton, half the criminals in the Bush regiem would have been behind bars.

Obama has a history of bringing opposite sides together, but this may wind up being his tragic flaw.  Be tough on corporate and political criminals and then make nice with the opposite side.  At least they'll respect whom they're dealing with.  They certainly never respected Clinton.
