The law enforcement community at the Federal level has failed to capture Charlie Rangel, Barak 0bama, Barney Frank, and a whole host of other miscreants. Why pick on Tiger? At least he was a bit more circumspect in philandering, and I don’t think he screwed the whole country...
They’re going after Tiger because he has money without power. Whenever you have money but not power, those with power will figure out a way to take your money so that they can buy more power.
