Gandhi once said:
"To disobey a law is a crime against the government.
  to obey an unjust law is a crime against humanity"

Every one is responsible, who makes the law and who enforces the law.
Take a look at telemarketing with their abusive, immoral, offensive and lack of respect phone calls.
Are these guys who make these calls innocent and good people just because they are only employees doing their job? No! they are not innocent, they are as guilty as the company that force them to do this.
If a company for which I work want that I do things that I consider, illegal, unlawful or unjust I will simple not do it, they can fire me, but I shall not do, even the case I can quit by myself.

The other case is when the law is not so wrong, but the person that enforces the law thinks that he is the Law. He interprets and enforce his own personal vision of the law and not what is the law itself.
This is common to happen with police and when s**t happens all the police runs to cover, plant and hide all the mess, protecting one each other.

And We, the artists, as Bush said "If you don't like leave the country", we as Obama said "Yes we can" we do it, the world is a big and a nice place.....

Stupidity also evolves!
