No, hiring a college sexual misconduct lawyer will not make you look guilty. It's not even a consideration on anybody's mind other than potentially yours in such a situation. It's definitely not on the school's mind. It's not on anybody's mind in that regard. It's a, say, paranoia that is just, unfortunately, altogether not appropriate to the circumstances. The simple question is, you have to ask yourself is that, is something at stake?
If you're accused of sexual misconduct at college, something is definitely a stake. Everything is in fact at stake, both in the short and potentially the long-term. You need to make sure that your interests are protected. You can't depend on the school to do that. Schools don't even play by their own rules in enough instances for it to be a concern. You have to do everything in your power to try to ensure a fair process and a favorable outcome. The best ally in that regard would be an experienced attorney advisor and they should be involved from the start of the process.
