NASHVILLE, Tenn. -- City leaders are asking a lot of questions about the security company hired to guard Metro buildings.

Video: Some Councilmen Call For Creation Of Metro Security Force

They said some of their concerns came after a Channel 4 I-Team investigation that uncovered guards whose company had been terminated back on the job in different uniforms.

Council members had a lot of questions for Mayor Karl Dean at a meeting on Friday including will Wackenhut Security keep its contract with Metro? The contract is good for another five years.

“Well they still have a contract,” he said.

But some Council members don’t think it should after a report on Channel 4.

Metro told Wackenhut to cut ties with a subcontractor, Specialized Security Consultants, which was providing security the night of the break-in at the Metro Election Commission.

But the I-Team discovered the same security officers were still on the job and had only changed to wearing Wackenhut shirts.

"I was shocked,” said Councilman Edith Taylor Langster.

Langster said she thought it was clear that the subcontractor was supposed to be out.

"It was my understanding the contract with the subcontractor was void,” she said.

"There is potentially a contractual dispute that's now in the hands of the law department,” Dean said.

Some council members said it's time for Metro to look at having its own city security force, and Councilman Michael Craddock was in favor of the force.

“There are some things that government does better than private industry, and maybe this is one of them,” he said.

Langster said she would like to see retired Metro police officers or firefighters working security jobs.

"I would like to see some of these officers, if they would like to, maybe come back to work 20 hours a week,” she said.

There's a lot of research to be done to see if that's a feasible idea including negotiations with labor unions and some serious number crunching about what a security force would cost.

The state comptroller's office is also going to audit the Election Commission and will focus on how it handle its computers.
