The protests against ICE have been going on for some time and gained new momentum after Pretti, 37, was shot dead by federal police on Saturday.
People are very upset, and it is a very tense situation, says Dag Blanck, professor of North American studies at Uppsala University.
Meanwhile, political tensions are heating up. Both Minneapolis Mayor Jacob Frey and Minnesota Governor Tim Walz are sharply criticizing ICE's actions. Kristi Noem, Secretary of Homeland Security, has claimed at a press conference that Frey and Walz are encouraging violence - and that Pretti was engaging in domestic terrorism.
Dag Blanck points out that US President Donald Trump has been criticized for immediately resorting to the concept of domestic terrorism when the mother of three, Renee Good, was shot dead in early January.
There could be a backlash for Donald Trump if public opinion begins to believe that this was not an act of terrorism and that he was murdered for no reason.
