"'Fake' IRS scandal spawns real coverup" (from USA Today).
For a scandal that is frequently derided as "fake," it is amazing how often real evidence disappears. The disappearing act is so frequent, it is reasonable to wonder whether it is really a systematic attempt to destroy evidence of abuse of power. . . .
To believe that the IRS scandal is the creation of President Obama's political opponents you have to believe an amazing series of events is just coincidence. That takes a more partisan cast of mind than to wonder whether this might be circumstantial evidence of a desperate effort to obstruct justice.
