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.

From picking your guests (always add a random) and your outfit, to coping with drunks and nudity, this is what you need to know

When I was young, I thought the worst thing you could do, as a host, was to run out of booze. Then, when I was less young, I thought it was to not have enough food, and now I am perfectly wise, I know that those things don’t matter at all, because you can always go to the shop. The important thing is not to look harried, and to not look that way, you need to not be that way.
