The trick is to get a video recorded instance where they have neither permission, a warrant nor RAS, and take your ID, then run it and make a comment about it.
Provided you can prove the stop was unlawful from the beginning, and show proof of the LEIN access, you'll have them.
What I'm not saying is that you'll for sure have the MSP going along with it. If the MSP doesn't get back to you with actions they'll be taking as a result of your complaint, it becomes time to complain to the Director of the MSP about the MSP officer's failure to do their jobs, complete with a case file of your entire complaint and all evidence you have, including all names, dates, times, and every other detail involving the MSP and the agency you're complaining about. I would suggest doing this quietly, and in a respectful, non hostile manner, just with a request that it get taken care of with as little additional commotion as possible.
If all this fails, think press release.
The MSP is among the best law enforcement agencies in this state. Though they have shown their flaws to an abnormal extent to this community, they have also helped us more than any other agency I can think of, apart from perhaps the OCSD after the 09 Boston Market incident. So, I would suggest treating them as they tend to treat others, professionally and respectfully, and give them the benefit of the doubt unless they completely and utterly fail to do their jobs.
