I think the Wall Street Protests are an effective example of freedom of speech and assembly. The cops cannot make these people leave the parks, they have to find ways around the law to get them out such as telling them they need to "clean" the parks because they cannot go against the first amendment, giving the people their right to assemble. It is also a great example of freedom of speech because these protestors are literally ripping on the government and the terrible job they have been doing with giving people jobs, publicly. The news may censor what they advise on television but the signs and speeches they give in public cannot be censored by an authoritative official trying to protect the government. These people have a strong opinion on this certain topic and they are using their first amendment rights to demonstrate them, as they should.
