A video showing Northampton police arresting a man who allegedly blocked the entrance to City Hall doesn't portray the whole story, the city's mayor said.

The video, which was posted to Facebook, shows 33-year-old Eric Matlock clinging to a railing on the steps in front of the building, as two police officers attempt to pull him away. He spits, and appears to gasp for air.
