NASHVILLE (AP) — The state Department of General Services billed Occupy Nashville $1,045 to provide two troopers for security the night before they began arresting the protesters and clearing their encampment.The invoice was part of a public records request to the department from The Associated Press.Protester Dorsey Malina said she was one of a group that met with General Services Commissioner Steve Cates on Oct. 26 over their concerns about security on the plaza.There is some disagreement about what happened at that meeting. Malina said a trooper who had been making the rounds of the plaza at night suddenly stopped showing up and protesters wanted to know why.They were told the state could not police their encampment and they would have to pay for security, she said.Jennifer Donnals, a spokeswoman with the Safety Department, said troopers never stopped patrolling the plaza and Safety officials who attended the meeting do not recall protesters ever raising that concern. They were concerned about safety, she said, so Cates suggested they hire security.Both sides say the protesters agreed to hire the troopers.
