"A federal judge has stopped enforcement of a Kentucky law barring non-citizens from carrying concealed deadly weapons. U.S. District Judge Thomas Russell said the law is written too broadly and violates the rights of attorney Alexander M. Say, a British national who has lived in Kentucky for 15 years. ...
The [ACLU] sued the Jefferson County Sheriff's Department and Kentucky State Police on behalf of Say. The ACLU challenged the citizenship requirement, saying Kentucky lawmakers should not have passed the law. ... Say argued that no federal law requires U.S. citizenship for people to be licensed to purchase, carry, transport or carry a concealed deadly weapon, and neither should state law."
