If it's Guiffre's evidence, why should she have to destroy it? I seriously hope she's smart enough not to do so (I think she is). Because if it's hers and she 'collected' it during her time with Epstein, then it belongs to her. Doesn't matter if it could be used against him or wasn't 'properly' collected. It belongs to her. She gets to keep it. What actually needs to be destroyed is the swamp creatures.
