According to the Des Moines Register, he was convicted of harassment in 2014 after police said he approached a man in the parking lot of his apartment complex, shined a flash light in his eyes and called him the “N-word.” Greene then told the man, “I will kill you, (expletive) kill you,” according to records.

He was sentenced to one year of probation. A probation discharge report filed in June 2015 shows that Greene received a mental health evaluation and “complied with the medication recommendations,” according to the newspaper.

He sounds like he should have access to firearms.
