Is there anyone who the Chinese government punished for tax evasion who turned out to be not cheating on their taxes? Selective enforcement is one thing. Fabricating charges is worse.
Similarly, in China today, everyone who is anyone in the apparatus is cheating taxes in some way, but it's brought up only if they become a problem for the leadership for some other reason.
Jailing after trial and due public process is one thing, "disappearing" people is another.
