Some first responders are coordinating their own effort to help curb street violence from the recent rash of attacks on Asians in San Francisco. The latest incident that left an Asian victim injured in a violent robbery where she was dragged behind the suspect vehicle has given the group of former and current firefighters another reason to respond. “We are going to be there in numbers and in strength and do what we need to do to defend these people,” said retired San Francisco Fire Department Fire Marshal Paul Chin. “We know the police officers can’t be everywhere. We wish,” said John Choy of the San Francisco Fire Department. San Francisco Police and the Sheriff guided the group of off-duty firefighters as they patrolled the streets of Chinatown for the first time Tuesday.
