[American_Centurion]

Not everyone freely uses their name in public.

Unless you were born cinFLA you are right now not using your name. There are lots of people who go by nicknames that are unrelated to their given name.

Would it be within my rights to tell a police officer that I am American_Centurion and give them no other name than that?

Regarding the automatic loss of the right to the 5th once they start testifying, to me that strengthens the argument that one should have the right to withold their name from police, since once they speak their name they may in fact be testifying right then.

This could turn out to be a very good/bad/ugly ruling from the USSC, depending on how they rule. I lean toward individual rights, but either way opens a can of legal worms.

Mr. Hiibel did.

If I were arrested and gave them cinFLA as my name, my rap sheet would read xxxxxxxxxx aka cinFLA.
