I've been watching a TV series recently called Person of Interest, it's really cool you should check it out. I'm curious though about people who somehow manage to completely wipe their identity and literally become a nobody and then aquire a new identity. I think legally the most thorough identity change comes from witness protection, but even then there are people in government who have files attaining to your true identity. On the assumption that you're never had your DNA or finger prints taken, I think the only way to completely become a new person, never to be identified ever again would be to fake your death and join the French Foreign Legion as I know they issue you with a new identity with French citizenship ect but then the question is, if you commited some kind of crime in another country and were arrested, you would only have a life history dating back to when you were issued your new ID, or would it be likely that the FFL would create a whole life background for you? Fake school, birth address ect? Just curious really, I think in this day and age, with the internet being what it is and everyone throwing their social lives onto it, there is no way to truely change ones identity? You'd need to change it so even if your mother saw you in the street and a full scale police investigation into your life went underway, you'd need your new ID to hold up... I highly doubt it's possible.
