So than you agree that the prostitute is the one judging herself?
Sorry for the late response: I didn't even see this post.
I can't imagine that she is the one judging herself. Judgment was carried out when it was demonstrated to the mob that she was an adulteress: either her husband/betrothed came with the accusation, or her father, or her lover. They may have had evidence. But judgment happened long before she got to where Jesus was. In fact, judgment is precisely why
she was where Jesus was - the mob had taken her to execute the sentence required by the judgment (which, before Christ intervened, there was the strictest of sentencing guidelines - specific punishments for each crime with no leeway, unlike most modern law systems which give options for most crimes, i.e. anywhere between 10 and 20 years, parole or no parole, etc.). In their time, judgment was probably carried out by the Rabbi of the town in accordance with the Torah, or by some other town official (sorry, I'm not too familiar with Jewish jurisprudence at the turn of the 1st century AD).
