When does "paperwork reduction" become "destroying evidence"?

Behold, the Bush Administration in chart form: Federal spending on paper shredding has increased more than 600 percent since George W. Bush took office. This chart, generated by usaspending.gov, the U.S. government's brand spanking new database of federal expenditures, shows spending on "contracts for paper shredding services" going back to 2000.

You be the judge.
