CHARLOTTE, N.C. -- All Mecklenburg County parks may soon be off limits to some people. County commissioners want to ban registered sex offenders from the county's 200-plus parks.

"You never know who is in the park," said Commissioner Bill James.

That’s why he’s proposing the ordinance banning sex offenders.

"It juts makes sense if your gonna ban sex offenders from schools and that’s a state law, the local law should have them banned from parks because that's where you have a lot of little children playing," James said.

He says the Mecklenburg County ordinance is modeled after one from the small mountain town of Woodfin, which passed one in 2005. The town faced opposition and a lawsuit from the ACLU, but just last month, the state Supreme Court ruled Woodfin’s ban did not violate sex offenders civil rights.

"They won, so now that it's legal, it's OK," James said.

More than OK with some parents we found at area parks.

"I think the sex offenders need to be kept out of parks," Denise Hall said while playing with her nephew on the swings.

But commissioners delayed voting on the ordinance until their next meeting, saying they had questions about how to enforce the law and its possible effectiveness.

Commission Chairwoman Jennifer Roberts said, “Parks with little kids, there are a lot of concerns so on face value it’s a great idea... (we) just gotta make sure it's done the right way."

Woodfin’s mayor says they haven’t had to make an arrest since the ordinance has been in place. He says it's easy to enforce there because the town only has three parks and 13 sex offenders – and the police know them all.

Mecklenburg County has more than 600 registered sex offenders.
