The simple answer to your complex question is NO. This is assuming that you live in a country where there are good laws (remember that history is full of bad governments that implemented bad laws) and that law enforcement is effective. Simplisticly, you should only ask yourself this question when your or your families life is being threatened and law enforcement is not around. Your response must still be within the constraints of your laws or you will find yourself in hot water. I'm not even going to try to discuss the ethics and morals that can apply as the situation can vary immensely. Keep it simple - don't operate outside the law, rather fight against unjust laws.
A nation's "sovereignty" allows it to exercise its political power and authority, since without sovereignty it is unlikely that the nation would be able to keep out outside powers and influence.
