Deporting Immigrants Arrested by Local Police Hasn’t Lowered Crime Rate, Study Finds

A study of Secure Communities—a Bush- and Obama-administration effort under which local police share arrested individuals' fingerprints with the Department of Homeland Security, which can then deport immigrant suspects who are undocumented or have criminal records—has found that the program does not lower crime rates, the New York Times reports.

Secure Communities is already controversial: A gainfully employed immigrant with no criminal record, for example, could find herself deported after being arrested for traffic violations. New York state, among others, has opted out of participation in the program, and the new study by a University of Chicago law professor and a New York University law professor is critical of its efficacy:

Secure Communities was rolled out over the course of several years, jurisdiction by jurisdiction, allowing the researchers to conduct essentially a randomized, controlled clinical trial to measure the effect of the policy.
Most efforts to study federal policy changes, Professor Cox said, become before-and-after experiments pivoting around one moment in time. But with Secure Communities, he said, “we were able to see the experiment repeated 3,000 times”...
They concluded that there was no “empirical evidence” that Secure Communities caused “a meaningful reduction” in the rates of serious crime.

How is this possible, given that 29 percent of the deportees studied had in fact committed “at least one aggravated felony or of at least two felonies punishable by more than a year in prison”? The study's authors suggest the answer might have to do with the rest of the deportees, many of whom committed only immigration-related crimes or no crimes at all. If the total group of deportees is no more or less law-abiding than other residents of the communities they're deported out of, it would follow logically that crime rates would ultimately be unaffected. More to come on this subject, hopefully.
