Fuck off. If he surrendered he will be killed. There is no way the billionaire class would allow a peasant like us to try to harm them and survive. They will also demonize him and drag him through the mud and claim he is a pedophile rapist who killed for pleasure.
IIRC, Snowden wasn't eligible for a jury trial, because he worked for the NSA and, so it they were pushing for a secret court-martial trial. Who knows if Snowden would have actually done it, but I remember he said he would return to the US if it were a jury trial.
Juries are specifically selected to avoid people capable of critical thinking, and people knowledgeable about jury nullification.
If it goes to trial his chances are slim. If he knows what's good from him, he's already in a foreign country with no extradition treaty, or halfway across the country in a remote section of wilderness laying low for the next few months.
