Legal question - Pilot liability and possible involvement with a crime

I write this question solely from an aviation point of view, and don't
wish to start any thread or discussion regarding the principal or
newsmaker involved.

What would happen if Michael Jackson wanted to flee the country in his
corporate jet? - specifically, would his corporate aviation department
(assuming he has one) agree to fly this mission if asked.

It's a purely theortical question, but I am curious whether a
professional pilot could be charged with a crime if he knowingly aided
a person avoid an arrest warrant. I would have to guess yes, though
I may be wrong. What if the corporate pilot did not know the reason
for his mission to fly abroad, just that he was told to do it (or
perhaps was misled - for example - he was told to pick someone up).
Does he have a duty to know the purpose of the mission/names of the
people aboard?

Any comments on this question from lawyers in this group or corporate
pilots would be appreciated.

Thanks,

John
