If someone is blairing [sic] music infront [sic] of my house when I'm trying to sleep can I call the police about a noise complaint or would that he violating their freedom of speech?
The issue is not the speech itself (music), but the method of delivery given a circumstance where one man's right to play that music conflicts with another's right to sleep peaceably in his own home.
ALL speech is protected. That said, the issue of conflict arises when the
manner of speech violates another's rights. This should be clear to all. Such violations do NOT, however, include butthurt. When someone says something that "upsets" another, onus lies with the recipient to deal with the utterances like a big boy. For example, if a man refers to a woman as a "stupid cunt", it is completely on the woman if she is "offended" by this. Racial epithets, ethnic slurs, and so forth are all the same insofar as responsibilities for butthurt are concerned.
The only utterances that are exceptions to this general rule are those that constitute "assault". If I tell you that I am going to kill you, it is well within your right to take action to preempt my stated intention to physically attack and harm you. Either way, I do not believe police have too much valid cause to interject themselves into such matters, much less the prosecutorial machinery of the "state".
What about threats are they protected by the first amendment?
IMO, yes they are. Equally protected, however, is my right to draw a pistol and shoot the ghost from your retarded self if you so threaten me, such words constituting legal "assault". Context is, of course, important. If one's older brother says "I'm gonna
kill you" in the ways traditional, there would be no basis for gunplay or other acts of violence against the utterer. But when circumstance allows for credibility of the perceived threat, anything goes as far as I am concerned. That is why I am a really big advocate of taking great care with one's words because they are very, VERY important. That we discount them into such cheapness by statute and government policy is a great shame upon us all. They have driven the common man into ever less wise habits of comportment in the presence of their fellows, which is why we are rushing toward the realization of a culture as depicted in "Idiocracy". As human stupidity becomes codified into "law" and men with guns act to enforce the infantility that arises therefrom, the population makes rapid its descent to that ever diminishing denominator. And that, my friends, is precisely what is happening in America right now as I type these sorrow-laden words.
