Both young people who were involved in the sexual act were badly drunk.  Decision processes of all are impaired when badly drunk.  Both parties chose to get badly drunk and must accept responsibility for their actions just as a drunk driver must accept responsibility for accidentally killing someone while badly drunk.  We will never know the details of the decisions made by the male and female drunks involved in this matter.  The girl was so drunk she didn't remember what happened.  So we will never know the extent to which there was consent or no consent.  Many folks are making many assumptions.  If the girl drunk doesn't even remember anything, she may well have given drunken consent even though when sober she would not have.  Similarly, the boy drunk may have accepted consent from the drunk girl even though he would not have if sober.  I am sorry but when people choose to get dead drunk in party situations, I think it is grossly unfair that only the boy bears responsibility.
