What would J. Edgar Hoover say if he were alive today?
It appears that FBI agents, including supervisors, cheated on an open-book test covering the FBI's policies for conducting surveillance on citizens of the good ol' US of A. Agents worked together, used cheat sheets or took advantage of a software problem to answer questions regarding how agents can conduct investigations without treading on the rights of the citizenry (there's that damn Fourth Amendment again).
These are the people who run domestic surveillance on groups that espouse views that could be considered anti-government. These are the people who collect data and evidence to use against those the government deems to be terrorists.
If they can't be trusted to take a test, how can they be trusted to carry out investigations in which the rights of the citizenry are under attack? If they will lie when signing an oath that they took the test without anyone's assistance, what's to stop them from lying on the stand?
