I went and looked up the law for carrying a gun in Minneapolis. This is the AI summary.
"In Minneapolis, like all of Minnesota, you need a state-issued Permit to Carry to carry a handgun (concealed or openly) in public, which requires training, a background check, and an application through your county sheriff, with licenses valid for 5 years and allowing carry across 33 states. Recent court rulings have clarified that 18-20 year olds can now obtain permits, but local city ordinances can still impose restrictions, so checking Minneapolis-specific rules is crucial.
Here is the state government webpage on this.

From what I have seen, the local police are reporting he was lawfully carrying his weapon. I need to find the video of him just standing there filming, which is not illegal to do. He was not impeding.
