I am sooo disappointed that Spitzer is resigning.

Cynthia - I'm bright enough to know that public figures-anyone, actually-should NOT be pedestalized. Appreciate their positives, acknowledge what you can learn from them, allow them to inspire, but don't act surprised when their imperfections show.
Sirs - I can't speak of knowledge of street-level prostitution, but from what I can glean via the internet it is actually safer to have meaningless consensual sex with a prostitute than with someone you meet at a bar. Anyone who has chosen to be in the profession will do their best to take care of themselves, which generally means testing, condom use, etc. After all, once your student loans are paid off do you really want HIV or HPV or whatever following you your whole life? Think about it.
