I had an experience with this fraud that was ALARMINGLY similar.  "Special" Agent Mungle is one of the biggest jokes I have encountered in my entire life.  He tries his hardest to intimidate you from the very start.  All I saw was a huge fatass that has no other skills and has to try and belittle others.

By the way, Mr. Mungle, I can tell you are an alcoholic.  Nice booze nose you piece of crap.  I know you read this too.  You specifically said you do.  By the way, I like how you flash your badge and claim you are a "special" agent.  You are NOT the same type of special forces special.  Think of yourself more like Special Education special you fraud.

This piece of work tried to accuse me of also lying on my SF-86. Completely false, I went through that thing with a fine tooth comb.  Then he also tried to accuse me of serious crimes.  Completely false as well.  I have never even got in so much trouble as a speeding ticket.  I was completely truthful on everything and I was called a liar.  He tries to say he can "help me" if I confess.  Confess to what?  I had not lied!

If I had any advice of future people that get contacted by Mungle, refuse it!  If anything, request someone else!  Call IA and tell them you don't want him as a examiner.  There is more than one examiner at that office, believe me.

On another note, isn't our government in debt?  How much money are we wasting paying these polygraphers?  We could be saving MILLIONS to get rid of them!
