In #Chicago on Sunday, dozens of #armed federal agents, in full #tactical gear, walked the streets of some of the city’s most prominent tourist & shopping [& safest] areas. That comes amid a surge of #immigration enforcement that began early this month, including repeated conflict at an #ICE building in #Broadview, west of Chicago, where federal authorities on Friday & Saturday fired #PepperSpray balls & #TearGas at #protesters.
