People are outraged over a video that shows officers stopping a self-identified physician from helping a 37-year-old Minneapolis woman who was shot and killed by a U.S. Immigration and Customs Enforcement officer.

One civil rights attorney and professor at Northwestern Pritzker School of Law who spoke to HuffPost broke down why she believes it would be worth pursuing a civil liability case over the “disturbing exchange.”

In the video seen above, captured by a bystander named Emily Heller and obtained by HuffPost, a man can be heard asking officers if he can check the victim’s pulse.

“No! Back up! Now!” an unidentified officer responds.

“I’m a physician,” the man says.
