Regarding getting the body cam footage, here are some relevant portions of Minnesota Statutes
Minn. Stat. § 13.825, subd. 1(b)(1)-(2)
(1) "portable recording system" means a device worn by a peace officer that is capable of both video and audio recording of the officer's activities and interactions with others or collecting digital multimedia evidence as part of an investigation;
(2) "portable recording system data" means audio or video data collected by a portable recording system
Minn. Stat. § 13.825, subd. 2(a)
Data collected by a portable recording system are private data on individuals or nonpublic data . . ..
Minn. Stat. § 13.825, subd. 2(g)
Any person may bring an action in the district court located in the county where portable recording system data are being maintained to authorize disclosure of data that are private or nonpublic under this section or to challenge a determination under paragraph (e) to redact or withhold access to portions of data because the data are clearly offensive to common sensibilities. The person bringing the action must give notice of the action to the law enforcement agency and subjects of the data, if known. The law enforcement agency must give notice to other subjects of the data, if known, who did not receive the notice from the person bringing the action. The court may order that all or part of the data be released to the public or to the person bringing the action. In making this determination, the court shall consider whether the benefit to the person bringing the action or to the public outweighs any harm to the public, to the law enforcement agency, or to a subject of the data and, if the action is challenging a determination under paragraph (e), whether the data are clearly offensive to common sensibilities. The data in dispute must be examined by the court in camera. This paragraph does not affect the right of a defendant in a criminal proceeding to obtain access to portable recording system data under the Rules of Criminal Procedure.
For those who don't want to read the actual statute,
