No one is forcing a person to get a tattoo
Never said that. Note the word "voluntarily".
No information can be pulled up on a person by scanning their tattoo.
I beg to differ. All police reports note "identifying marks, scars, tattoos..." for identifying persons of interest. As you said, tattoos are individualistic, and permanent (for all intents and purposes). A simple quick way to identify someone is by a mark they can't easily change, like a scar, birthmark, or...a tattoo. But, that's not really my curiosity in this. I'm just interested in the psychology of getting a tattoo. As you said, it's a mark of individuality, but aren't there plenty ways to be an individual without the discomfort and permanent-ness of having ink injected under skin?
