A single counter example-- Kat Von D. She's a famous tattoo artist with a cluster of small stars tattooed on her face.

Another counter example-- I knew a guy who got teardrop tattoos on his face and he's just a dude who likes shitty tattoos. He's an artist and ne'er-do-well but really doesn't have any designs on being a gangster.

You know, you're able to make inferences based on bias too. How do you know that this isn't one of them?
