By supporting and urging a boycott of several bands and musicians it seems that the FOP may be endangering the lives of many people. I imagine that this doesn't simply mean that police won't buy cds. It most likely means that members of the Fraternal Order of Police will be encouraged not to provide security for the bands mentioned or for their fans or, perhaps, for those who might be listening to music by the aforementioned artists. True, you can't falsely yell fire in a crowded theater. In 1969 the Supreme Court ruled that the only speech which can legally be censored is incendiary speech.
Incendiary speech is that which reaches the direct incitement to imminent lawless action.
Or in other words, speech which would directly cause harm to others. It is an idea to be seriously considered. As I said, Mass Mic is concerned with protecting everyone's free speech, the police seem to be concerned with protecting no one but themselves. Nina Return to Mass. M.I.C home page.
