The Occupy Wall Street movement kicked off in New York nearly a year ago, and for most of that time the response from police has been monitored across the country.

In total they found 130 incidents of excessive or unwarranted force. John Knefel of Radio Dispatch joins RT's Kristine Frazao from New York to explain.
