I have seen a great deal written here about the right of free expression, and I agree with most of it, but I regret that I have seen very little about the responsibility that goes with that right. As the judge told the street fighter, "Your rights end where the other fellow's nose starts." A singer certainly has the right to express his ideas, up to the point where they begin interfering with the continuance of our society. "Cop Killer" is not only (IMHO) bad music, it is contra-survival to our civilization. It is anarchy. It is a wish to return to the days when the man with the biggest stick, the longest sword, the most powerful gun could do whatever he wanted to, with no consideration for anyone else. Our society has designated the police as a force to keep the strong and lawless under control for the protection of the weak. To advocate killing police officers strikes at the core of civilization. We as a society (or our elected representatives) have the responsibility to control and counter that attack. If the people will not do it, the government must.
Pete M said, "Those of us from Europe have had first hand experience in the not so distant past of where democratically elected governments can go if allowed." If allowed. Once again the abdication of personal responsibility. We saw it happen in Germany, in Russia, in China, in Cuba, in so many countries. First, "We must stand together." Then, "You must stand behind the government." Then, "Give us your guns, the government will protect you." And finally, "We have all the guns, you will do as we say." It's happening again, in Australia, in Britain, in Canada. People who will not take responsibility must take whatever is handed them.
