Remember Scooter Libby? Or Martha Stewart? Both of these high profile people were prosecuted for making false statements to federal agents. As a general rule, I would never ever talk to the FBI or any other federal investigator because if I made a mistake, I could still be prosecuted for that innocent mistake, even if it isn't intentional.
Apparently, if you do the same thing in your senate confirmation, well, it's just not that big of a deal. Combining this, with the DOJ dismissal of the Black Panther Voter Intimidation case and the dismissal of the ACORN investigation, and you realize that there are two kinds of justice in this country. One for Democrats and their friends, and one for the rest of us.
Guess which one goes to jail.
