Do you know how FBI interviews work? It is a crime to lie to them, a felony. Pound me in the ass federal prison time in fact.

Essentially in effect, if you make a material statement that is false in ANY WAY, they can decide to send you to prison.  If they ask you the color of the socks you were wearing and you thought they were white, but they were actually grey, you are in violation of the law. If you thought you had lunch with some one at 2:15 and it was 2:17, you can get sent to prison.

Essentially if they get more than about 5 minutes to talk to you they will be able to find some technicality to prosecute you over, or force you to plead guilty to a lesser charge.....
