Can I have full immunity or liability relinquished prior to any possible legal acts/offenses of a certain nature? For example, say I'm hired to be the voice of a public image that one day may be associated with terrorism. Is it possible that I can be granted immunity in such a case so that I am not liable for terrorism because I only voice such a begin -- and do not actually control them/their actions?
I know this may not be specifically easy to form an idea around, but I feel that someone will get this.
For example, say I request immunity in the case that a certain group I wish to work for is in legal trouble. I want immunity because I do not want to be charged with a crime that the group commits, not me, even though I may be the representative or CEO/etc. of such a company, group, or etc.
Is this possible? How does this work & under what conditions can immunity be granted beforehand?
