Protesters critical of corporate influence over politics and who want higher taxes on wealthy individuals continued to march on Wall Street this weekend, resulting in some 80 arrests for disorderly conduct.

Members of the movement, dubbed Occupy Wall Street, claim many of the arrests were unwarranted, and videos taken by spectators show what appears to be particularly rough handling of the protestors by police.

NYPD spokesman Paul Browne said, "Those who resist arrest can expect some measure of force."

But demonstrator and military widow Elena Spence, 23, claims, "It turned so quickly from something very peaceful to something very scary, and the violence wasn't instigated by any of the protesters. It was instigated by the cops."

In one particular incident, video shows a group of young women corralled by police with a mesh barrier being pepper-sprayed. Browne said those people "confronted officers and tried to prevent them from deploying a mesh barrier - something that was edited out or otherwise not captured in the video."

Other videos depict protestors being roughly thrown to the ground before being arrested.

Those tweeting from the protests -- under the hashtag #OccupyWallStreet -- report that individuals with cameras and video cameras seem the most heavily targeted by police.

Regardless, demonstrators have come from all over the country to make their voices heard.

"I actually quit my job and got a one-way ticket here for the protests," said Casey O'Neill of Oakland, California. "I just felt like in a lot ways this was the last hope for some type of real change."
