I warned a co-worker of the IRS Scam.  She got a message on her home machine from a person by the name of Officer Simon Jackson, with an Indian accent telling her that she was being sued for tax evasion by the IRS.  Gave this number to call but the caller id number on her phone was 202-622-3000 (that number rings but no answer.  I called on her behalf and when I wouldn't give her full name or phone number they began to use extreme vulgar language at me. I hung up on them and reported the scam to the IRS.
