[E. Pluribus Unum]

I know Godwin's law will be invoked on me, but there is precedence for this:

[Defiant]

It is not a good analogy. The government isn't stamping people with identifying numbers. The thugs and criminals are stamping themselves with unique identifying characteristics, like a thumbprint that can be spied from a block away. Keeping a database of these when they are collected from people who have been convicted of a crime is just smart law enforcement.

I would oppose it if they are getting information about people from tattoo artists before anyone has committed a crime, or if they are stripping people down and photographing their tattoos when they are charged with a crime, but not convicted. If that is going on, it is an invasion of privacy, but still not similar to Hitler giving numbers to Jews. Godwin was right again.
