And percentages don't matter here: facing a whopping federal deficit combined with limited resources at the IRS (thanks to GOP stripping the IRS budget), it only makes sense to go after the bigger fish to fry, i.e. the absolute figure of $340 bil. vs. measly $9 bil. Also, despite the IRS freezing hundreds of thousands of refund checks for the poor due to suspicion of fraud, when such folks pressed the IRS it was found that 2/3 of them deserved their check (no fraud), adding credence to my suggestion that much of the "fraud" by the poor is likely due to innocent filing ignorance.
[The White House] is explicitly reserving the right to abuse prisoners, while denying them any opportunity to seek redress in court. Having publicly accepted the ban on cruel, inhuman or degrading treatment, Mr. Bush is planning to ignore it whenever he chooses.
