In theory, a reasonable suspicion is established by the prosecution, and approved by a judge, prior to a warrant being issued. This is often further reviewed, by a judge, prior to the extradition request.

I make no claims about this specific case, but that's how it's supposed to work. There have been cases of unlawful renditions, but this doesn't appear to be that and those matters don't usually show up in court. It's not perfect, but reasonable suspicion is what warrants are based on.

I don't necessarily disagree with what you said, but the variable "reasonable" here is of course up for debate, since suspicion is very easy to have.

We don't know the specifics, yes, but the evidence presented in these types of cases is not exactly compelling.

MalwareNews kid made a tweet about some malware.

The Temple professor who was also a Chinese national was wrongfully arrested while "trying to flee the USA with trade secrets." He is now suing the FBI.

BTC-E guy was snatched up in Greece after traveling from Russia for vacation. We don't know the details, but presumably if he really thought he was a truly wanted cyber criminal, he would have never left.

And Gottfrid Svartholm was extradited from Cambodia to Sweden, without an extradition treaty!!!! All so he could be tried for copyright crimes against US corporations.

So, for these reasons, I am hesitant to say that this Chinese guy in particular without a doubt is guilty, just because he was arrested (snatched up.)

People are not "just swiped up". A grand jury is presented with base facts and asked to issue an indictment so that the suspects can be arrested. Without the issuance of a True Bill (indictment) the investigation must continue but no arrests can be made. Since they apparently received the indictment and warrants issued arrests were made. Now it goes to court where the prosecution must prove guilt beyond a reasonable doubt.

If these people did nothing wrong they will have the opportunity to present their defense. But just an aside, these are not the only occurances where our law enforcement must wait for individuals to leave a non-extradition country in order to gain access to make an arrest. It happens with suspected drug dealers, murders, etc

Please see my other comment for more context about the USA's shoddy record as of late.

I don't disagree with you that we have a process, but apparently these warrants and indictments aren't particularly difficult to get. Maybe there is a bias towards granting indictments against foreign nationals?

Or maybe I am completely wrong, and the feds did an amazing job finding a true criminal.

Based on past evidence, I am not holding my breath that this time the feds have really found a criminal. See my other comment for a recent list, especially the one of the Chinese-national professor who worked at Temple.

So, for that reason, I refuse to take any US indictment seriously, unless the evidence is painfully clear (El Chapo.)
