What is the approval process for buying body armor? Doesn’t it require msp approval?
It shouldn't require approval, unless the person wanting to purchase has been convicted of a violent crime, or drug trafficking:

only a person with a prior conviction for a crime of violence or a drug trafficking crime as defined in the statutes listed on the left side of the page, must apply to use, possess or purchase bullet proof body armor. Before you may use, possess or purchase bullet proof body armor, your application must be approved.
