Responsibility to wear protection

Re the creep who kept having unprotected sex after being diagnosed with HIV and now finds his mug all over the media, Phil at Finland for Thought asks:

Should the police publicly oust HIV-infected people like this? Or should the responsibility be solely placed on the sex partners to wear protection?

When two people have sex, placing the responsibility for wearing protection solely on one person would be absurd - doubly so when the person who would escape responsibility is the one who knew protection was definitely needed.

Secondly, it's not an either/or question. The police publishing this guy's name and picture doesn't reduce anyone's responsibility to wear protection. People are not going to say to themselves, "If my partner has HIV, I can just read about it in the tabloids afterwards. There's no point in using a condom."
