An advisory panel has recommended that Waukesha County sheriff’s deputies be allowed to identify illegal immigrant suspects and hold them until federal enforcers can pick them up. Waukesha could be the first in Wisconsin to be approved for the controversial federal program, after the immigrant rights group Voces De La Frontera said Tuesday that Milwaukee County’s request was turned down. Former Milwaukee Sheriff David Clarke spoke highly of what he called the “deputizing” of his former officers as immigration enforcers — but Waukesha Sheriff Eric Severson says the effort does not go that far, even though critics say it would erode trust between police and immigrants. The Office of Immigration and Customs Enforcement must still give final approval to Waukesha County’s request, and Severson expects a decision within four weeks.
