He was carrying around an AR-15 in Portland, Maine, simply because he could.
Maine allows firearms to be carried openly in public.
Police began receiving calls about 11 a.m. and located the unidentified man carrying an AR-15-style semiautomatic rifle along a popular recreation trail that loops around the city’s Back Cove. The gun was fitted with a high-capacity magazine.
The man “identified himself as an open carry activist who was exercising his Second Amendment rights” under Maine law to openly carry an unloaded firearm in public, according to a police news release. Police said he was not violating any laws or ordinances.
The Portland Press Herald writes that the man “recorded his conversation with police, who made sure the man knew the law before letting him go about his business.”
