Bill Anderson via Lew but original link to report now gone. It's 2010 and not the first report I've read of this kind of malfeasance.
In order to ensure that FBI agents knew the law on domestic surveillance, they had to take a test. They were not supposed to have help or have anything around to give them answers, with Question #51 asking if anyone assisted the test taker.
Naturally, the agents cheated, and then lied about it. You and I can go to prison for five years for “making false statements,” but even though FBI agents made false statements, you can bet nothing will happen to them.
