Green's conviction about this is tantalizing but it's also melodramatic in a way that makes it easy to believe something not quite true (or provable, anyway.) In fact if you look down the thread, you'll see Green admitting that correlating Salter is basically speculation and other people providing plausible alternatives to Green's claims for Salter's motives at AWS. tptacek has a more measured history of what actually happened and it is very different than what you'd glean from Green's tweets.[0] Personally in this case I'd be more worried about touting Ring's end-to-end encryption with one hand while the other hand points one of those ends to your police department[1].
