A Dallas ISD teacher charged in connection with a July 4 protest over mass deportations that ended in gunfire outside an ICE detention center in Johnson County says he had no involvement in the violence.

Authorities say the protest , organized by the Socialist Rifle Association, turned violent when someone ambushed police officers responding to the scene. One officer was shot and wounded. Since then, at least 17 people have been arrested, including Dario Sanchez, who says he had nothing to do with the violence.

"I haven't committed any crime," Sanchez told CBS News Texas in an exclusive interview. "I had no idea that anything violent happened. My politics is not about violence or anything like that."
