The NYPD will release enhanced images from a YouTube video which appears to show six suspects who swarmed two lieutenants during a protest on the Brooklyn Bridge.

The alleged assaults happened while the authorities were trying to arrest a part-time professor, who was allegedly caught trying to throw a trash bin over a bridge railing and onto a lower roadway.

“They not only have a right to go after them, they have a duty to go after them,” Judge Andrew Napolitano said of the suspects today on “The Real Story.”

He told Gretchen Carlson, “The First Amendment requires the government to give breathing room to protests. Nobody gives breathing room better than the NYPD.”
