Equipped with cellphones and cameras, protesters from Occupy Wall Street have recorded and released several videos showing interactions between demonstrators and the New York Police Department that have raised their profile and won them sympathy in the battle for public opinion.

Now the Police Department has staked out ground in that battle by releasing videos of its own.

One of the videos, released on Sunday morning after hundreds of people were arrested the day before for walking on the roadway of the Brooklyn Bridge, shows a police official warning protesters that if they crossed the roadway, rather than the pedestrian walkway, they would be charged with disorderly conduct.

His remarks were met with chants of “Take the bridge.” Seconds later, the protesters began marching across the bridge, accompanied by cheers.

About 700 protesters were eventually arrested, and many claimed that the police had not warned them but instead tricked them, allowing them onto the bridge’s roadway, and even escorting them part of the way across, only to trap them in orange netting after hundreds had entered.
