About two dozen protesters demonstrated in front of the Mission Valley offices of Blue Shield today. Three people were arrested after they marched into the building and refused to leave.
The protest began mid-morning outside the Blue Shield building. Marchers wanted Blue Shield to stop spending money lobbying against health care reform.
Protesters soon walked into the building, and tried to get in the Blue Shield office. The door was locked.
Protester Mary Bell said she wouldn't leave until someone came out to talk.
"We've tried everything else," Bell said. "We rally every week, we write letters, we call. So we're just trying to have someone pay attention."
Bell and two others locked arms at the building's entrance. Police eventually arrested them, and charged them with trespassing.
