yes, it's true that taking nearly 3 years to raid him is odd. That said, even though this article is from 2016, it does say the following:   "Platte River, the Denver firm hired to host the Clinton family’s e-mail server four months after Hillary Clinton left her secretary of state post, has said it fully cooperated with the FBI and other government agencies during the investigation"  (from https://www.denverpost.com/2016/09/09/platte-river-networks-employees-ordered-house-committee-hearing/) ISPs of that nature have backups upon backups, and they've supposedly cooperated with the investigation. I'm fairly sure that there exists a backup in the hands of someone at Platte River Networks containing whatever content Combetta tried to Bleachbit-away (though it is conceivable that as an admin, he'd have access to some/all of that backed up data and could have deleted it also, but doing that would also certainly set off alarm bells - it's not like ISPs with full data centers only have a single admin). But you're right, it's odd that a raid took this long to occur, and even stranger that he hasn't been suicided (even though he did repeatedly just plead the 5th and wouldn't really say anything at that congressional hearing).
