Most of us take a summons for jury duty seriously, but enough people skip out on their civic duty that a new and ominous kind of scam has surfaced. The phone rings, you pick it up, and the caller identifies himself as an officer of the court. He says you failed to report for jury duty and that a warrant is out for your arrest. You say you never received a notice. To clear it up, the caller says hell need some information for verification purposes - your birth date, social security number, maybe even a credit card number. This is when you should hang up the phone. Its a scam. This scam has been reported so far in 11 states, and is particularly insidious because the scammers, pretending they are with the court system, use intimidation to bully people into giving information. As a rule, court officers never ask for confidential information over the phone; they generally correspond with prospective jurors via mail. The FBI and the federal court system have issued nationwide alerts on their websites, warning consumers about the fraud.
