peter chaoPaying taxes is pretty offensive to a lot of people, would you be prepared to go to jail so that you did not have to pay taxes? I would much rather pay taxes.
It's the same situation when you recieve a subpoena. You can ask and recieve immunity for your own criminal acts, now the feds are asking you to do your share in their investigation of a possible crime against the U.S.. To me, that's a reasonable request and much more preferable than sitting in jail.
