Fifteen years ago, the City of Chicago adopted a “gun offender registry” ordinance that requires convicted gun offenders to register with the police and have police monitor anyone listed in the registry. The ordinance was intended as a violent crime prevention strategy, a community resource, and a law enforcement/officer safety tool, with the thinking being that the registration and ongoing monitoring would deter registered criminals from re-offending and ensure their speedy apprehension should they commit new crimes.
True to the usual gap between gun control theory and reality, that hasn’t happened.
The ordinance itself was enacted as a clapback to the landmark ruling of McDonald v. City of Chicago (2010). In that case, which arose out of a challenge to a Chicago ordinance that effectively banned private citizens from owning handguns, the United States Supreme Court held that the Second Amendment applied to states and political subdivisions. The registry ordinance was passed in a special Chicago council meeting that repealed the ordinance that McDonald invalidated and promptly replaced it with the registry ordinance, purporting “to protect the City from the unique and heightened risk of firearm violence, especially handgun violence, endemic in densely populated urban areas.”
The ordinance requires that any Chicago resident convicted of a “gun offense” register, in-person, with the Chicago Police Department (CPD) within five days of release from imprisonment or at the time sentence is imposed. “Gun offense” is broadly defined to include, besides unlawful possession by a prohibited person, a wide range of violent crimes using or involving firearms. As a registration precondition, the CPD must provide written notice regarding the duty to register to each offender within the scope of the ordinance.
The registration information includes the offender’s photograph, fingerprints, home and work address, phone number, and copy of a driver’s license or state photo ID card. Following the initial registration, the offender must re-register annually over the next four years, unless a new qualifying conviction occurs. The information is fed into a “gun offender registry” maintained by the CPD for use in law enforcement locally and beyond.
A CPD policy mandates that officers who encounter convicted gun offenders must determine whether the offender is registered and take action accordingly (a violation of the registration requirement attracts criminal liability in the form of fines and potential incarceration, with each day that the violation exists constituting a separate offense). Police Districts must also conduct annual “criminal registrant visitations” (of all registered individuals) and “semi-annual gun offender registration missions” (visiting offenders known to be in violation of the ordinance).
The ordinance also has a “community notification feature,” in which the names and addresses of all registered gun offenders are posted and updated in a CPD website, with a searchable database that maps the city-block location of registered offenders “within 1/8, 1/4 and 1/2 mile of an identified address.”
By 2017, it was apparent that the ordinance and registry were not living up to expectations. A newspaper indicated there were less than 2,000 individuals listed in the registry; further, a significant percentage of offenders were not registering, and only 100 arrests were identified for failing to register. “It defies logic to think that there are less than 2,000 convicted gun offenders in the City of Chicago,” said one Chicago alderman, adding, “There is a glitch in the system somewhere.”
Now, eight years later, the City of Chicago’s Office of the Inspector General (OIG) has released a report following a comprehensive review of the implementation and enforcement of the ordinance, uncovering a number of problems and deficiencies. Supporters “have argued that the Gun Offender Registry can serve as a public safety tool, a resource for law enforcement, and a deterrent to crime. However, little evidence exists suggesting that the Ordinance or the registry has fulfilled these intended goals.”
The findings in the 75-page report, released this month, include the lack of a baseline. The “OIG was unable to identify a population of gun offenders qualifying for registration by which to assess the completeness of the Gun Offender Registry and CPD’s enforcement efforts for gun offender registration” because of limitations in the available conviction data. A lack of effective communication and controls between custodial institutions and the CPD prevented the issuance of the necessary notices to all qualifying offenders. The communication issues included incorrect information (“OIG found that CPD’s ‘Gun Offender Rules and Regulations’ includes four [municipal code] statutes that have been repealed” and omitted an assault weapon crime that should have been included). The CPD provided inconsistent information about where and when gun offenders could register, with reports of excessive wait times and long lines at both registration sites, one within a “gang-controlled area.” One CPD member reportedly called the conditions a “drive-by waiting to happen.”
The CPD also failed to comply “with its own policies to monitor or pursue registered or unregistered gun offenders… CPD reported to OIG that gun offender registrant visitations have never occurred, and Gun Offender Registration Missions have not occurred since December 2021.” Even when offenders were arrested for non-compliance, the City’s law department generally opted not to pursue violations to the full extent allowed. The report states that out of 443 arrests over a 21-month period, 91.0% “ended in non-suits, where charges were dismissed because prosecution was declined” for a variety of reasons.
Compounding these issues, there was no systematic review or audits to ensure the accuracy or validity of registrant information, and individuals remained on the registry past the four-year expiration date. The OIG’s analysis of records as of March 2022 revealed that “anywhere from 2.9% to 9.8% of records were improperly included;” a 2025 analysis revealed a couple of records with expiration dates in 2099 and several more with no expiration date at all.
Overall, the report reveals that the ordinance and registry have been nothing short of abject failures. The ordinance not only failed under every metric the OIG used but likely diverted scarce public resources from more effective public safety uses.
The expected deterrent effect on gun crime, or crime in general, could not be evaluated, as the OIG concluded that the goal of deterring crime was the one aspect of the ordinance “least susceptible to measurement.” While arrest rates are not true indicators of guilt or crime, the OIG used a random sample of 355 gun offenders on the registry as of 2022 and found that over half (192, or 54.1%) had been arrested “at least once” by the CPD while registered. The “charges were wide-ranging in severity, from minor traffic violations to homicide,” and of that sample, 84 registrants (23.7%) were rearrested at least once on gun-related charges, “including one registrant with six gun-related charges.”
The OIG concluded that data errors and lack of accuracy prevented the registry from being a useful law enforcement tool. The CPD did not require officers to consult the registry when responding to 911 calls, executing search warrants, or conducting traffic or investigatory stops, and CPD had other resources that provided the same information. If anything, the ordinance burdened already stretched law enforcement resources, with no corresponding time savings or public safety benefits.
The registry fell flat as a community resource, too. There was no way to determine how often the public used the gun offender registry information. The City’s website lumped it in the same public data application as the sex offender registry, making it impossible to determine whether and how often the public searched only for gun offender information. City agencies that were supposed to rely on the registry (e.g., the Chicago Housing Authority) almost unanimously reported being unaware of the registry’s existence. One unfortunate and unintended consequence was the potential (as found in Baltimore) that homes within a defined radius of an identified ex-gun offender’s location experienced a decline in property values.
Even assuming that the ordinance had been implemented as intended, one Chicago public official pointed to the obvious flaw in its underlying rationale. Creating a list of past offenders is “not how gun violence works,” as “individuals who are committing crimes are often not caught by CPD and, therefore, are not convicted nor registered as gun offenders.”
In a press release about the registry law analysis, Chicago’s Inspector General recommends that if the costs of compliant implementation and enforcement “outweigh the impact of this particular tool, then we ought not stand it up as window dressing… If we are wasting time and law enforcement resources on the incomplete implementation of a tool that was never built to work in the first place, we ought to put that aside and invest in things that work.”
The Chicago experience is instructive for any other jurisdiction that is already spending taxpayer funds on, or is considering using, a gun offender registry because of its supposed deterrent effect on crime. Baltimore, New York, and Washington D.C. have gun offender registry laws, and consistent with the results in Chicago, the OIG’s report specifies it “was unable to find publicly available figures on the effect of the registries on gun-related crime rates in New York and Washington D.C. and found that recent studies have questioned the utility and identified negative impacts of Baltimore’s gun offender registry.”
At its inception, the Chicago registry was highly touted by its proponents and their media cheerleaders as a major leap forward in fighting “gun violence.”
It’s failure to deliver as promised (or, virtually, at all) is a lesson that should be remembered when the “next big thing” in “gun violence prevention” has its day in the public eye.
