as for the original, what if it was your daughter question: Rape to me is quite possibly one of the worst offences man has devised. It is animalistic, though it is a HUMAN trait (though I've heard that alpha-male monkeys do this to lesser males to establish dominance, but, no malice involved). For a man to voluntarily give up his humanity like this, he deserves a type of justice for which no law is written.
Nobody here seems to be advocating vigilantism, nor do I condone it. But...until I miraculously gain absolute executive power (i.e. Thanos' Infinity Gauntlet or something equally proposterous), EVERBODY can and will do as they wish. I may not agree with your position, but I'll defend your right to it.
I would have given the woman some jail time, some probation. I wouldn't have congratulated her or given her a medal. She did break a LAW, and must be punished. However, like Blackmind said, she is (was) a threat only to the rapist, while the rapist was a threat to society.
Sorry for all the "justices" in my posts...I can't think of a word equally apt.
