How far can we go morally when protesting for justice?

When it comes to issues of morality, you're basically on your own. What I find to be moral you may not. Bin Laden felt morally justified in blowing up the twin towers because he sees the United States as an evil empire. Would you agree? The Jews felt morally justified in asking the Roman's to crucify Jesus because He was a threat to their theology (to put it simply.) There are people who justify smoking marajuana even though it is illegal because they feel the law is immoral. Basically, you have to make decisions based on your own morals and willingness to deal with the consequences of your actions.
