And the reasonable doubt would come from someone else could have used my account, does the service's account ID match the account ID for my user name, nothing was found on my devices, did the IPs match my known IPs, when did the access take place vs where was I, etc.
Your comment was already asked and answered several times in this HN post.
There was evidence of a crime, only the Kik account ownership evidence was thin. Any decent lawyer would have probed into that aspect of the case, but there are lots of comments here about failures of defense / prosecution / experts / legal system.
They had the exchange with a minor from an account that everyone -- including the defense -- believed to be Klayme's. His only counterargument was that his email had been hacked, which was not true and not the correct explanation.
But what they didn't have is any independent evidence that Klayme had sent the messages or even that he had access to the account that sent them. If they had looked at the IP address from which the messages were sent, they would have seen that it wasn't his and was in a distant geographic location.
Residential proxies exist. Even if they had picked up that the IP was from somewhere else, a decent lawyer could probably have been able to convince a jury that just showed intent because he was trying to conceal his IP.
You'd have to show some evidence that he did conceal his IP, otherwise there should still be reasonable doubt. You can make up whatever you want without evidence, proving it is different.
You're talking nonsense. Among other things, had either the prosecution or the defense seen that the IP addresses didn't match, they would have pursued it further. "The IP addresses don't match but that just proves that the defendant tried to hide their IP address" is a ridiculous corrupt argument, one that a decent prosecutor would never make ... please do not ever serve on a jury.
> Prosecution: Mister Klayme, the criminal messages were sent from a Kik username called "fus ro dah". What's your Kik username?
> Klayme: It's "fus ro dah".
> Prosecution: It logically follows that Mister Klayme was the sender, and is therefore guilty of the offense.
