What Chicago's fight against ICE can teach us all about how to resist oppression | Zoe Williams

A harrowing US podcast documents a community's struggle against immigration raids - and warns us about herd mentality

Earlier this year, the Trump administration reversed the convention that nobody would be snatched by immigration and customs enforcement, or ICE, by a school, church or hospital. Since then, teachers have reported classrooms a third empty, as parents are too scared to send their kids in - volunteers walk them there and back.

In the Rogers Park area of Chicago, a group of citizens are organising to resist such immigration raids. Sometimes, it's simple non-violent tactics, such as slowing officers down by walking in front of them. Last month, 50 people rushed to a church, where the congregation was trapped, having got word that there were ICE agents waiting outside. Maybe their most evocative tactic is whistles - coded blasts for when a convoy is suspected to be ICE agents, a different code when it's confirmed. They have numerous accounts of undocumented migrants warned off driving right into a raid, which is galvanising, but they also see and hear dismaying things all the time: vehicles standing empty, one door open, not robbed, merely relieved of their drivers; landscape gardeners arrested off ladders. Earlier this month, the Protect Rogers Park group got 1,500 calls in a day.
