And your second example basically says 'we will prevent you from defending yourself, so just take it and hope the system saves you'.
And if you think this culture 'supports rapists and demonizes survivors', you are in need of getting your facts straight.
EDIT:
I'm beginning to take this whole thing a bit personal. I learned a long time ago to call it quits when that starts to happen on the internet, so I'm out.
My second example was to highlight that people defending themselves faces more prosecution than those actually committing assaults. The system will not help you, generally speaking, if you are a survivor of sexual assault and you are likely to be prosecuted for defending yourself. That is a part of rape culture, btw, the legal indifference towards rapists.
For an overview of rape culture, which is a real thing, see: http://www.shakesville.com/2009/10/rape-culture-101.html
People on here were stating that the woman should get a gun, or get pepper spray, or get a taser. Telling women they need to defend themselves in a certain way and it's on them to get a gun and shoot an attacker is what I and a few others were upset about.
Most US states frown heavily upon indiscriminate gunfire as a communication tool, even in cases entirely unlike that one where the shooter is in danger.
* Most people who are sexually assaulted know their attacker and are not attacked randomly on the street. This makes self defense scenarios unrealistic, as there is already some level of trust between an attacker and the survivor
* Most sexual assaults will go without arrests and prosecution. There have already been cases where women have been arrested and sent to jail for self defense (CeCe Mcdonald's case comes to mind), including the Marissa Alexander case where someone fired a warning shot at their abuser and was sent to jail: http://en.wikipedia.org/wiki/Angela_Corey#Marissa_Alexander_...
* Sexual assault and rape aren't just about incidents, it is about a culture that supports rapists and demonizes survivors and dismantling that culture is the best way to defeat sexual assault
