One of the drivers who rammed the law enforcement vehicle was armed with a semi-automatic weapon,” McLaughlin said in her post. Law enforcement also deployed gas canisters at the protesters, according to footage from Reuters. At protests against the immigration enforcement action, law enforcement has used force and tear gas against demonstrators, including lawmakers. “Today in Chicago, members of our brave law enforcement were attacked—rammed and boxed in by ten vehicles, including an attacker with a semi-automatic weapon. If you see a law enforcement officer today, thank them,” Noem posted on X.
