Minneapolis on edge amid protests

This weekend, tens of thousands took to the streets in anti-ICE demonstrations nationwide in Minneapolis braving subfreezing weather to mark where 37-year-old Renee Nicole Macklin Good was shot and killed by an ICE agent. Days after the fatal shooting, you could see that hundreds of protesters are still showing up. Minneapolis is a city still on edge. They're saying immigrants are welcome here, demanding answers and a fair investigation. State investigators say federal officials have denied them access to evidence in the investigation of Good's death. The current posture is that the investigation is one that the Feds want to do without state involvement.

Sources tell CBS News the Department of Homeland Security is planning to send hundreds of additional US Customs and Border Protection agents to the Twin Cities this month, adding to a footprint of roughly 2,400 DHS personnel. On Saturday, Democratic members from Minnesota, including Representative Ilhan Omar, were blocked from touring an ICE detention facility just outside of Minneapolis. What happened today is a blatant attempt to obstruct members of Congress from doing their oversight duties.

A CBS News analysis has found ICE agents have fired their weapons in at least eight incidents over the past four months, resulting in three deaths. Nearly all of the shootings involved vehicles. Cell phone video, amplified by the White House, shows ICE agent Jonathan Ross's point of view-- I say, go get yourself some lunch, big boy.

--and what are likely Good's last words. That's fine, dude. I'm not mad at you.

The refrain now memorialized by mourners and protesters alike. CBS News has learned prosecutors within the Justice Department's Civil Rights Division will also not join the FBI's investigation, breaking with past practice and raising further questions about just how far the federal inquiry will go. Margaret. That's Nicole Sganga in Minneapolis.
