The following has been validated as NOT being a hoax by snopes.com and
TruthorFiction.com.  In any case, it's good common sense advice at the
end.

You could get a phone call from someone claiming that you failed to
show up for jury duty and that a warrant has been issued for your arrest.

 The caller then wants to confirm your personal information such as Social
Security number and other financial data.  Authorities in several
states have issued news releases about the scam including in Arizona, Iowa,
Washington, Arkansas, Illinois, New Jersey, South Dakota, and Utah as
well as Canada. The Better Business Bureau of North Alabama issued an
alert.

If you get any inquiries for your personal financial information,
Social Security number, ATM pin numbers, passwords, etc. don't give it.
Instead, make direct contact with the organization claiming to want it
and verify that the request was really from them.
