I voted other, because there's two different problems that blame could be assigned to, them getting attacked and them being put in a situation where they were likely to be attacked. For the first obviously there's only one person to blame, the person who attacked them. For the second, you are not at all to blame. I don't understand why so many people think that getting drunk voids you of any responsibility for your actions. They chose to get drunk so they decided that they would risk the lack of judgment. I'm not by any means saying that this means they are responsible for being attacked, as I mentioned this is all on the person who attacked them, but they are responsible for putting themselves in the situation that they're blaming you for.
