From Indianz:
The city council in Manistee, Michigan, voted in favor of a mutual aid agreement with the Little River Band of Ottawa Indians.
The tribe is offering its officers free of charge. The city police chief said the service is crucial.
“There are many times when there’s only one police car working the entire county outside of the city. My concern is someone’s going to dial 9-1-1 and no one’s going to be available to respond,” said chief Dave Bachman, WPBN-TV reported.
The agreement lasts one year.

If one of these tribal officers engages in negligent or unlawful acts in the course of policing in the area of Manastee will the tribe be liable for any damages? Because of a quirk in federal case law decisions dating to 1920, Indian tribes and their employees are able to evade all of the state and local laws which apply to everyone else and they cannot be sued for their misconduct or misdeeds no matter how outrageous. What is the liablility of Manastee in such a case? What law enforcement qualifications and standards apply to these tribal officers ? Are they they same for the hiring and job performance as required of the non-tribal officers? How will Manastee control these “tribal police officers” or enforce any standards and regulations in light of the fact the tribe and it’s government is immune from state and local laws and from being sued for their liability?
I bet if you read the agreement, all of those questions are answered, just as they have been in all the other law enforcement agreements between tribes and cities or counties in Michigan.
