Collateral arrests of immigrants have risen even in states without viral raids.

West Virginia arrested over 10% of its noncitizen population in 8 months with the help of 287(g) agreements with police & ICE. State and local involvement produces long-term deportations.

That said, hardcore federal surges like we saw in Minneapolis, Chicago, L.A. are an effective way to net a bunch of people and could be feasible if ICE, CBP have even better community support e.g. to operate detention facilities.
