Another tough spot for a DA. The article doesn't indicate if the other 2 women also had previous consensual relations with the accused.
The thing I'm left with as a result of each of these cases for women that are assaulted/raped*:
- contact the police immediately, and only provide the basic facts ("Johnny raped me in my room at midnight")
- insist on a medical check ("rape kit") before getting cleaned up
- get the necessary support/help (counselor/therapist, lawyer, friend, etc.).
A decision on whether or not to press charges can be made later. Not providing the physical evidence can (and likely will) prevent a victim from pursuing "justice" at a later date.
* yes, I realize that this is a traumatic, emotional, experience. It just seems that potential victims are best served by having contemplated "what I will/should do in case I've been attacked" scenarios.
