Todd Gitlin, a professor of journalism and sociology at Columbia University in New York, spoke to Al Jazeera about the Occupy protest movement in the US.<br /><br />He said that the movement reflected "anger at the impunity with which the wealthy walked away from the consequences of having brought down the world economy."<br /><br />"It is anger at a system of inequality that has been entrenched and normal. There is a collective wish for a system that is more humane."<br /><br />He also said he expects Occupy protests to intensify in 2012.<br /><br />"I think well see more attempts to take over buildings that have been foreclosed. We will also see protests directed at specific banks, at specific political candidates."
