Anyone heard of freedom of speech? Apparently our good friends at the NYPD haven't -- they shut down a protest right after Cindy Sheehan spoke, and arrested one man for using electronic amplification equipment in the park where the demonstration was. This is the same park where musicians, breakdancers, magicians, and every sort of performer come and blast their music and give shows. Could this possibly be any more blatant a violation of free speech?
