According to Tucson Unified School District Board Member Adelita Grijalva, the students shown in the video chanting and chaining themselves to public property are simply practicing "civil discourse."
Grijalva: "They [students] organzied themselves very well tonight."
Reporter: "And are you disappointed by any of their actions?"
Grijalva: "No, no. I think that they are using their right for civil discourse."
Tucson reporter Mike Shaw has the story.
