I saw Bishop Barber talking about this.

Cities across the US have citizen organized #ICE rapid response crews, but in #LosAngeles they have formalized these teams into "Liberty Vans." Each van carries a lawyer, a faith leader, and a videographer to document ICE raids and initiate community support.

We've all seen how ICE agents run from faith leaders and crowds of ordinary white people, so imagine the response when a van with three professionals rolls up.
