As I've said before, if he's really this stand up guy, why did he run? IF he really had good and legal reasons to do what he did, take it to court and face the music.
I know, right? Like how the Sons of Liberty didn't disguise themselves as Indians before dumping a load of tea into Boston Harbor, and then when done, turned themselves in to the nearest British garrison? We need more heroes like those fine, upstanding, nametag-wearing gentlemen.
if you break the law to make your point that the law is unjust you should stand ready to be arrested, imprisoned and tried in court for what you choose to do.
"Ready to be" doesn't mean adopting a Gump level of naivete and making it easy for the government to remove you from the public view.

If he had stuck around, we would all have forgotten about him as soon as the next weekly scandal distracted the media.
