Yesterday while passing through a busy place, somewhere I pass through regularly, I noticed a busker who I recognized as the ex of someone I used to know. He lied to this person about his sexual history and his HIV status, and transmitted the virus to them. He also tried to hook up with me, lying again about his status, not knowing that I knew. While I don't want to promote criminalization of HIV, I don't know that I would mind if he were prosecuted. Perhaps that's what it would take to make him stop lying to prospective sexual partners.
