I'm going to go out on a limb and say that yeah, sexual assault is fundamentally different than other forms of assault.  I'm also in the rational camp that says women (and men in certain settings) would do well to mitigate some obviously dangerous situations.  Most of us instinctively know you don't walk through the roughest parts of town flashing wads of cash.  And although we all know it's wrong to steal, I think most would agree the victim in this example exercised poor judement.
