Protesters across the United States staged widespread “no work, no school, no shopping” strikes on Friday, shutting businesses, walking out of classrooms and gathering in city centres to oppose the Trump administration’s immigration crackdown, as anger mounted over the killings of two people during recent enforcement actions.According to news agency AP, the demonstrations came amid outrage over the killing of Alex Pretti, an intensive care nurse who was shot multiple times after using his cellphone to record Border Patrol officers during an immigration enforcement operation in Minneapolis. His death followed the January 7 killing of Renee Good, who was fatally shot while sitting behind the wheel of her vehicle by a US Immigration and Customs Enforcement (ICE) officer, deepening scrutiny of federal tactics.Organisers called for a nationwide shutdown, urging Americans to abstain from work, school and shopping. “The people of the Twin Cities have shown the way for the whole country — to stop ICE’s reign of terror, we need to SHUT IT DOWN,” read one of several messages circulated online promoting protests across communities, as per AP.
