A scandal has erupted at a tattoo studio in Racine County (Wisconsin) that strikes at the most vulnerable point of tattoo culture — the trust that a client and artist must place in each other within a private room. Former police officer Caleb Mackenzie, 30, has been charged with second-degree sexual assault: according to the prosecution, on August 22, he forced a tattoo artist with whom he had a scheduled session into a sexual act. The case quickly moved beyond a typical criminal story because the defendant, as it turned out, had been on the so-called Brady list since January — a registry of law enforcement officers who have been flagged by investigations regarding the credibility of their testimony.
