I love the presumptive guilt that the media and this forum seem to have.
The charges are being brought to an Article 32 hearing. It's the equivalent of a grand jury in the civilian world. They'll determine whether or not the allegations are substantiated and have enough evidence to proceed to a court-martial (trial).
Cadet Evenson has been "in limbo" here for quite some time. I have interacted with him on a few occasions since 2011's graduation in May. I can't speak to the others because I don't know them. Raimus is right, there is a ton that happens here outside of what is reported to the media.
Of the 33 or whatever alleged sexual assaults last year, we were only told of maybe 6 that I can recall. Why is that? I dont know how the numbers work, but I'd venture to guess that the number reported (33) weren't all investigated and successfully prosecuted.
These are very serious allegations, and no doubt there was at least SOME wrongdoing in each of the cases (underage drinking, abuse of a leadership position, etc). Whether or not it was as serious as alleged will be determined by the Article 32 and Courts-martial. It's excellent that USAFA is reporting like we should be. And yes, it's called "the zoo" for a reason. This is one of those reasons. Everything at the service academies is under a microscope, and for good reason; but you're absolutely wrong if you think that any of the academies is a worse-off place for women than a civilian university. Do a little digging and you'll see that. We've had people from civilian schools come tell us how bad it is/used to be, and how schools cover it up all the time.
There is no magic bullet to prevent these things from occurring. Teach your kids how to act, how to treat women, how to act around alcohol. This kind of conduct, if true, is absolutely deplorable. But talk to any of the cadet girls here, and most will feel like USAFA10s.
