I once was on a committee to craft a sexual assault and harassment policy for a small organization. It was an impossible task: You can't expose others, and especially the alleged victim, to a violent felon; imagine if they struck again! You also can't cost someone their job, residence, or reputation over an unsubstantiated allegation. And a small organization lacks the resources to do a valid investigation, conduct hearings, etc.

You absolutely can and should treat the complainant with respect and support; nobody accused them of a crime and they should not be treated with suspicion or doubt.
