These are not mutually exclusive.

We can extend our hearts and offer our support to the anonymous authors of these stories, seriously investigate the questions they raise, and prosecute to our fullest abilities all wrongdoings substantiated by credible reports (e.g. Susan Fowler's blogpost), while simultaneously being careful to restrict any punishment meted out to be only based on credible evidence.

"Believe victims" means offer support instead of minimizing ("I'm sure he didn't mean it") or making counteraccusations ("what were you wearing?"). It doesn't mean "automatically, immediately punish anyone accused of anything without due process".
