Identity theft is a horrifying and traumatic experience. It's easy to imagine the frustration at being wrongly denied a credit card or loan. Worse are the sleepless nights after threatening phone calls from creditors anxious to retrieve cash loaned in your name. It can also be much more serious. Identity theft is linked to organised crime in illegal immigration and human trafficking, drug couriers, and money laundering: for these criminals, identity theft is a way of avoiding detection.
