Earl Tuesday morning New York police broke up the OWS camp. Other camps have been broken up in the last few days. Michael Moore sees this as a coordinated action, possibly overseen by President Obama himself. I see it as the natural course of events.
Two factors converged to end the camps. The first was the increasing violence and health risk of the camps. In New York they had an ailment known as "Zuccotti cough". Drug-resistant tuberculosis is becoming associated with the camps, caught from the homeless who moved in with them. Drug use is common. The camps are becoming known for rapes and body counts. With all of this going on, it is hard for a mayor to condone the camps.
The second factor is that all of these problems made the mainstream news. Most sites began lumping all of the OWS coverage into a daily roundup that was seldom sympathetic to the movement. Without public support the camps were vulnerable.
Keep in mind that there is no free speech issue here. Someone cannot take public land and insist that the land it forfeit in the interests of free speech. The Occupiers planned on making their camps as permanent as possible. The light, nylon tents were to be replaced with heavier military tents for the winter. Possibly by spring they would be building solid structures.
Also, camping in public spaces is not a recognized part of speech. It was invented for this event. The Occupiers can still assemble in the parks, the just cannot camp.
