Should there be laws governing racist comments made at rallies that  incite violance?:
Although we have free speech in America if our speech incites a riot or if it is reasonable to assume that what you say could incite others to do harm or break the law then there can be legal repercussions.  The reason this so seldom happens though is because it has to be proved that the actions of others were the direct and sole result of the words or actions of another and this can be hard to do.
