Funny thing to say, since you live in Atlanta! Anyway, good for her! I guarantee the attacker will never, ever, do that again!
If he attacked her first, then it was self defense. I would let her walk for the manslaughter and give her a fine of public mischief for parading the head through town.
She's pretty much screwed unless she has a goodly amount of money, and for something this public even that might not help her. Indian society, while more liberal towards women than most other Asian societies, isn't exactly pro-woman, even acting in self defense. I expect that she's going to be locked up for life and probably abused by the guards.
I say bronze the head and give it to her on national TV (or radio whatever they have over there) and let it be a lesson to all assholes.
Make her a Bollywood star and she can pump out four movies per week, cutting off a different shitbag's head in each film! When the director yells "CUT" he isn't kidding!
What is the difference between a drug dealer and a hooker? A hooker can wash her crack and sell it again.
The moral of the story: Don't stalk and sexually harrass and she won't cut your fucking perv head off.
