A federal mediator will return to North Minneapolis on Thursday, hoping to improve relations between the predominently African-American community and the Minneapolis Police Department in the wake of last week's riot. Right after the incident, Patricia Glenn visited the community and conducted preliminary talks. Glenn, who's based in Chicago, has extensive experience mediating between law enforcement and communities of color. She helped when Cincinnatti exploded in riots after a string of police shootings. She says the meetings in Minneapolis last week were a good start.
