I've collected three statements of people who saw your wink and smile at Ken Clark and then have the tape of what he said thereafter.  The smart thing to do was simply apologize for your office's mistake, which apparently you won't do.  You should not accuse someone of being delinquent on their taxes without having your ducks in a row.  I'm not sure what your education is, but such an accusation is called "slander per se."  I gave  you a chance to act like a normal human being who made a mistake.  I suggest  you contact legal counsel.  I tried to be nice to you but I'm now done with you.  Your investigation is bogus just like your information you provided to Ken Clark.  You really should not have picked a fight with me.  I will be seeing you soon.
