You have my sincere apologies if my words struck wrong with you, as that was not the intent at all - more of a show of my disdain towards him & his crimes & that is where it ends.
If you haven’t read the extensive interviews from Grissom, they will likely change your mind regarding his level of intelligence. He can figure out devices, PCs & such but his abilities at even approaching credibility as even a halfway decent liar are just an insult to liars. He just talks in circles for the most part. Lots of "you don’t understand me."
ETA:
No, not at all. He had 30 some odd CSAM charges & that was just on what they did find. He had 1 device that was hidden from which he was able to delete data prior to LE getting ahold of it. His dad, who was the homeowner & paid for the WiFi was never charged with a thing, ironically.
