(AP) — Iowa law enforcement officials are debating the wisdom of granting gun permits to blind people.

Iowa law doesn’t allow sheriffs to deny a permit to carry a gun in public based on physical ability.

Some sheriffs have been granting gun permits to people with visual impairments while others have been denying them.

Jane Hudson with Disability Rights Iowa says keeping legally blind people from obtaining weapon permits would violate the Americans with Disabilities Act.

Some other states, including Nebraska, require anyone applying for a gun permit to provide proof of their visual ability by supplying a driver’s license or doctor’s statement.
