Good show. Evidence is never something that to look for: just get a scientist to find it for you.

As for Buffy, I tend to agree with your recollection. You might want to give the series a break, though - if it's meeting the law at 50%, then that's equivalent in terms of time to a feature film meeting the law. (It's not as though there are very many conversations in Buffy between two men about something other than a woman, after all.)
