SHELBY COUNTY, Alabama -- A half-dozen or so law enforcement vehicles converged on a polling location in Pelham this afternoon in at least the third report of someone trying to bring a gun into the polling locations in Shelby County today.

This afternoon in Pelham, a report surfaced of a man wearing a shirt that stated "Bama Carry" wanting to bring a firearm into the Pelham First Baptist Church Annex on U.S. Highway 31. The man had a camera phone displayed and was recording his experience, a witness told AL.com.

Sometime this morning, a man named John David Murphy wore his holstered 9mm pistol with two clips into First United Methodist Church of Alabaster. Murphy told The Associated Press he would complain to Shelby County authorities about having to put his gun in his truck before voting.

Sheriff Chris Curry in an interview this afternoon said another man at a polling location wore a gun into the building, voted and was leaving when someone noticed his holstered pistol. Curry could not recall the polling location of the third encounter, and the man left before anyone spoke to him.

No one was arrested today in any of the three incidents, Curry said. All were non-violent encounters. "We've got 121,000 registered voters in Shelby County. We've had three instances of someone with a gun at a polling place, so when you put it in that perspective, it doesn't rise to that much of a issue," he said.

"It's about voting. It's not about guns. It's about voting," Curry said.

All of the polling sites in Shelby County have signs posted that prohibit firearms, said Kimberly Melton, chief clerk of the Shelby County Probate Court in Columbiana.

"All precincts have no-weapons signs posted for the safety of the voters," Melton said in a phone interview this afternoon.

She referred inquiries about complaints received by the Probate Court concerning the firearms ban to the Shelby County Sheriff's Office, which handles security for the polling sites.

Elsewhere in Alabama, the issue of firearms at polling locations has become a discussion topic today. Some Chambers County voters complained and the sheriff removed "no guns allowed" signs from most polling places today.

According to a post on the Chambers County Sheriff's Department Facebook page, Sheriff Sid Lockhart and Judge Brandy Clark Easlick met and determined that state law didn't prohibit guns from being carried into polling places.

"However, voters are reminded that no weapons are allowed in the courthouse or schools. We apologize for any inconvenience that may have caused," the Facebook post stated.

In Pelham, one witness spoke with a man intending to carry a gun into the polling location. Luke Camara, campaign manager for Alabama House District 73 Republican candidate Matt Fridy, said he saw about six or seven law enforcement vehicles arrive at the Pelham First Baptist Church Annex a little before 3 p.m.

"All of a sudden there were just all these cops show up. I was like, 'What the heck is going on?'" Camara said in a phone interview.

There were personnel in Shelby County Sheriff and Pelham police vehicles. "They had a little meeting and spread out around the parking lot here to see what was going on," Camara said.

"We were out waving to people and a guy in a convertible pulled up. ... We started talking," Camara said. "He said, 'I'm about to bring my firearm in here and they're going to tell me I can't, and it's my constitutional right.'"

The man was wearing a "Bama Carry" shirt, Camara said. "He parked his car and got out. He had his camera phone out and he was recording already. He did the whole thing to do a publicity thing," he said. "The police officers showed him the sign on the door and they had a discussion."

Camara spoke with a sheriff's deputy who said the man with the gun had called the Shelby County Probate Court to complain about the prohibition on firearms at polling sites.

Curry said he was unsure if the man at the Pelham site returned to vote, but the other two incidents ended with the men casting their ballots. "Two of the them voted and one of them didn't unless he came back later," he said.
