On the first day of his second term, Present Trump signed an executive order taking aim at “so-called sanctuary jurisdictions,” marking his latest attempt to step up immigration enforcement in progressive, pro-immigrant communities. While there’s no universal definition as to what constitutes “sanctuary” jurisdictions, the most accepted definition are communities that limit state and local law enforcement participation with Immigration and Customs Enforcement (ICE), enforcement program known as Secure Communities (S-Comm).
S-Comm is, essentially, a nationwide immigration screening program. It has long been commonplace for jails to share an individual’s name and biometric information (e.g., photo, fingerprints, etc.) with federal authorities to see if the person has a criminal record or any outstanding warrants when an individual is arrested and booked. S-Comm further shares this information with ICE, which screens the individual for immigration violations.
If ICE suspects an individual of being in the country without proper authorization, it can issue an ICE detainer, which requests the jail to hold the individual for up to 48 hours so that ICE can take custody of the person and begin deportation proceedings. ICE can, and frequently does, detain individuals under S-Comm regardless of whether the charges for the original arrest are dropped. From the time S-Comm became nationwide operational in 2013 through 2020, roughly 700,00 individuals were removed from the country.
S-Comm was (and still is) controversial. Numerous local governments, mostly counties, have passed various measures in opposition to the program. Other governments went further, explicitly prohibiting their officers from contacting ICE and prohibiting their agencies from spending money in ways that otherwise could help ICE. However, other governments essentially did the opposite with some states requiring their counties to honor ICE detainer requests.
In our PSJ article, we examined the extent to which state and local governments play a role in implementing federal policy, focusing on the patterns of interaction between federal actors and nonfederal actors implementing S-Comm. Specifically, we examine the extent to which localities and states could hinder or help with the program’s implementation.
To determine what role these subnational policies could play, we collected county-level ICE removal data and information about which states and localities adopted policies aimed at either helping ICE by mandating their agencies honor detainer requests or hindering ICE’s efforts prohibiting that they cooperate with ICE’s detainer requests.
We found that states and counties can indeed play a prominent role. Taking these various other factors into account, counties that passed so-called “sanctuary” ordinances saw roughly 30% fewer deportations. Counties in states that had passed their own state-level “sanctuary” laws saw a similar decline. States that passed legislation requiring their localities to cooperate with ICE saw 44% more deportations.
We also wanted to determine to what extent the presence of the cooperative and noncooperative policies was reflected in what ICE itself was doing. It is one thing for counties and states to simply refuse to cooperate; it is entirely another for ICE to modify its own behavior because of these policies. To do this, we redirected the variables to determine whether they could help explain the extent to which ICE was making detainer requests in the first place. Again, we found that ICE was making fewer detainer requests in states and counties where cooperation with ICE was prohibited and making more in states where the counties were directed to cooperate.
Considering the ongoing debate over immigration enforcement policies, our findings underscore the significant impact of state and local policies on the implementation of federal initiatives, like S-Comm. The presence of subnational policies not only shape the outcome of the policy, but also how the federal agencies, like ICE, behave when implementing federal programs.
