County Jail to take persons into immigration custody during a two-year period
between 2019 and 2021 “attributed to our partnership with the Waukesha County
Sheriff’s office.”

With a detainer, ICE asks local law enforcement to keep custody
of a person for up to 48 hours after any state law basis to detain them ends.
During the Trump administration, ICE devised the warrant service officer (WSO)
program, a new form of 287(g) agreement, to authorize local law enforcement agents
to serve immigration detainers and retain custody of immigrants under those
detainers. DHS described the WSO program as an attempt to shield local officers
from liability when they violate people’s rights, and as a way to subvert state and
local decisions not to participate in immigration enforcement.

It requires only a
single day of training for law enforcement partners.

WSO agreements have proved popular among Wisconsin sheriffs. The first sheriff in
Wisconsin to sign a WSO agreement was in Sheboygan County, where the sheriff
signed a new WSO agreement referring to it as a “partnership” with ICE.
14
Documents disclosed to the ACLU of Wisconsin in response to open records requests
showed that the Sheboygan sheriff then encouraged other sheriffs to sign such
agreements.
15
Other WSO contracts have come out of ICE participation in statewide conferences of
Wisconsin sheriffs. During the course of 2020, sheriffs in Brown, Fond du Lac,
Lafayette, Manitowoc, Marquette, and Waushara counties also signed WSO
agreements.
16
In many counties, the agreements were entered into without any
input from the local community. In fact, none of these agreements were approved by
county boards or publicly acknowledged by these sheriff’s departments until the
ACLU of Wisconsin disclosed their existence.
