MT. VERNON (WSIL) -- A pair of southern Illinois towns are at the top of the list when it comes to not complying with certain FOID regulations.
The Chicago Tribune reports 78 percent of people since 2015 failed to follow up with law enforcement.
Mt. Vernon tops the list of noncompliance with 10.4 people/1,000 residents who didn't account for their weapons.
Marion is third with a noncompliance rate of 7.5 violators per one-thousand people.
Jefferson County Sheriff Jeff Bullard said Illinois State Police handles all the investigations.
"If it is someone who would be considered a clear and present danger, a potential violent offender, then we will help the state police in their endeavors to investigate revoked FOIDs that have not been turned in," Bullard said.
Bullard said in his experience, instances of violence involving someone with a revoked FOID card are rare.
"Most violent offenders are people who never had a FOID card to begin with and also were FOID card ineligible, meaning through their criminal history they could not get a FOID card if they applied for one," Bullard said.
Lawmakers started developing tougher FOID restrictions after a man in February killed five people in Aurora with a gun he shouldn't have been able to buy or own.
Several law enforcement agencies in the Chicagoland area have teams dedicated to FOID revocations, but Bullard said he'll only help with tracking noncompliant offenders if the suspect presents a clear and present danger.
He said the FOID card system violates the second amendment of the constitution and some people lose their cards for minor infractions, like failure to get it renewed.
"We have to balance that protection of the community and protection of people's constitutional rights," Bullard said.
