The emails were SENT to him, how is that not hard to understand?
Ah, the old 'the emails were sent to me by hackers and somehow none of my filters were working that day' defence.
Firstly, lie detectors don't work, which is why their results are not admissible in court.
Secondly, this 'testimony' comes from Benjamin Szemkus, a lying fantasist nobody. It's worthless. Notice how he's desperate to cram all the usual targets into his claim: Alefantis, Humal, Weiner, Schneiderman, and Daniels. It's such a blatant fabrication, he might as well add Chelsea Clinton at this stage to complete the set.
Thirdly, Szemkus first came out with this nonsense all the way back in June 2018. The police have done absolutely nothing with it since then, because they know it's ********. The whole thing is neatly debunked here.
Fourthly, no-one has ever provided any evidence of a genuine snuff video. They don't exist. It's an urban legend.
