Police: Medford Man Protesting Rumsfeld Used Karate Chop on Cop

A Medford man was arrested in Boston Monday after he allegedly karate chopped a police officer during a protest of Donald Rumsfeld.

Shaun Joseph, 31 of Medford is charged with Assault and Battery on a Police Officer and Resisting Arrest.

Joseph was part of a large group protesting a speaking engagement by the former Defense Secretary at the Old South Meeting House in Boston about 5 p.m. Monday, according to a Boston Police blog post.

Joseph was using a megaphone, and police told him he couldn't use it without a permit, the report said. Joseph gave the megaphone to another protester, and police told that person not to use it as well.

But as an officer was talking to that person, Joseph "walked over to the officer and struck him across the forearm using a karate chop technique," the post said.

A struggle ensued and Joseph was arrested with the help of other officers.
