FORT MYERS, Fla. -- A group of controversial clowns are coming to downtown Fort Myers, but some critics worry it will lead to trouble.

The Insane Clown Posse is a rap duo whose music focuses on violence and mayhem.

Monday night, despite some concerns from one councilman, the city council gave the music group the green light to perform at Harborside Event Center  in October.

They say it's a matter of free speech, and that the council can't judge one group over another. Also, there's already a contract in place, so October 8th, the show will go on.

From their violent lyrics to their colorful fans, the Insane Clown Posse concerns Fort Myers council member Tom Leonardo. "In their lack of dress, painted as they are, and I've seen photos of them covered with blood...I don't think this will be good for our city," Leonardo said.

In 2011 the FBI described the rap group's fans, who call themselves Juggalos, as a "loosely-organized hybrid gang."

Several supporters have even been arrested for murder with the crimes mimicking the lyrics in certain ICP songs.

But Ragen St. Peter, with Ragemore Events, who booked the group for Harborside Event Center, says this stigma of violence simply isn't true.

"The band members themselves are the most awesome, down to earth, coolest guys you will ever meet," he said.

In an interview with ABC News four years ago, the group sat down to say their violent music -- is simply -- just that.

Fort Myers Police Chief Doug Baker says the city will have additional police officers on duty, come concert-time. "What we assign to, from a resource standpoint, will send a message of what's going to be tolerated, and what won't be," said Chief Baker.

Chief Baker tells WINK News that cost of police presence will either be picked up by Harorside, the concert promoter or the city, which would mean taxpayer money.
