Can you get totally wiped from the governments system?

You can't. Fingerprints and teeth can be eliminated. But once they have your DNA, you are screwed. Except they don't even need your DNA. The DNA of your child, a sibling or your parents will do the trick.

Sorry.

How does the government get your DNA? When you're born? Because that's the only time I've been to a hospital or such thing. I mean if I were to completely leave the system and go abroad then they wouldn't be able to find a family member if I eliminate my finger prints and teeth; I don't have any children.

Have you ever combed your hair?
Have you ever worn clothing?

Well... if you go abroad, then there is a chance that they will never think to check your DNA (although I think they get information for you to get a passport).

If you went to North Korea, for example, there would be little chance for the American or European governments to track you.

May I ask why you want to do such a thing? The purpose of evading the government dictates the effectiveness of certain techniques.

Um....which is it? Not been in a hospital since you were born or, as written in another of your topics, you've been in psychiatric hospitals?

I've been in a psychiatric hospital yes so I suppose they have my blood but that's it. I'm just wondering if it were possible to erase yourself.

Not the past...going into the future, if you are very careful and clever, you might get away with it for a little while. Isn't that what fugitives attempt to do?

In theory yes, in practice no chance in hell.
