The state of Minnesota and the cities of Minneapolis and Saint Paul have filed a lawsuit against the Department of Homeland Security to end the "unlawful, unprecedented surge of the federal law enforcement agents into Minnesota," Minnesota Attorney General Keith Ellison said at a news conference on Monday.

Video of a U.S. immigration agent fatally shooting a Minneapolis mother in her car on Wednesday has divided the nation, becoming a political Rorschach test that elicits different verdicts depending on who views it.

Federal agents are carrying out immigration arrests in Minnesota’s Twin Cities region already shaken by the fatal shooting of a woman.

Renee Nicole Good's death sparked protests in large and small cities across the country, which are expected to continue throughout the weekend.

The move has deepened doubts, already raised by Minnesota officials, about whether the shooting will receive a fair and scrupulous examination.

The woman shot and killed by an Immigration and Customs Enforcement agent in Minneapolis was a loving mother, a poet and a partner whose family – along with neighbors across her stunned city and strangers far beyond – is shocked by the circumstances surrounding her death.
