A prolonged legal battle over public records has exposed hundreds of customer complaints regarding the private canine security firm patrolling the Chicago Transit Authority. The disclosure comes after a local attorney took the agency to court, alleging the transit authority systematically violated state transparency statutes to conceal records regarding its multimillion-dollar private security contractor.
The controversy surrounds Action K9 Security, a private firm operating under an $89.6 million taxpayer-funded contract with the CTA. For over a decade, guards dressed in black uniforms and accompanied by muzzled German Shepherds have patrolled train platforms across Chicago. Their primary mandate includes handling platform infractions such as fare evasion, loitering, and smoking.
As the nation's second-largest public transportation network, the CTA has faced increasing scrutiny over passenger safety and has actively sought to rehabilitate its public image. However, transparency advocates and riders have raised serious questions about the oversight and accountability of the private contractors tasked with maintaining order on transit platforms.
Public concern escalated dramatically following a violent altercation on July 9, 2025, at the Red Line’s 69th Street station. A brawl involving four men and contracted canine handlers broke out on the platform and was captured on video, later circulating widely on social media after being posted by the account Chitown Crime Chasers.
The footage depicted scenes of intense chaos as punches and garbage cans were thrown. During the scuffle, a German Shepherd bit both assailants and its own handlers without receiving commands, while one security guard tumbled directly onto the train tracks. The incident triggered an influx of public complaints demanding an inquiry into the training standards of both the dogs and their handlers.
Chicago attorney Conley Wouters was among those alarmed by the platform incident, noting that his initial concern stemmed from what appeared to be the mistreatment and improper management of the patrol animals. Seeking greater clarity, Wouters filed requests under the Illinois Freedom of Information Act to obtain the CTA's contract with Action K9 along with any documented complaints involving the firm.
Despite the legal mandate of the Freedom of Information Act, the transit authority failed to provide the requested documentation for months. The continued lack of response prompted Wouters to seek administrative intervention through the Illinois Attorney General’s Public Access Counselor, the state body responsible for reviewing improperly denied or ignored public records requests.
Following an independent formal review, the Public Access Counselor determined that the CTA had violated state open records law and formally directed the agency to produce the requested materials to Wouters. Even with that directive, the agency released only a fraction of the documents before lapsing back into silence.
Faced with ongoing stonewalling from the transit authority, Wouters filed a civil lawsuit against the CTA the following July. It ultimately took nearly an entire year from his initial public records request for the agency to finally surrender the complete cache of documents detailing its relationship with Action K9 Security.
The newly released files revealed a total of 133 customer complaints filed against Action K9 Security since 2022. The records documented widespread commuter unease regarding the physical condition, demeanor, and readiness of the contractor's working animals on busy rail platforms.
Among the most notable grievances was a formal report authored by one of the CTA’s own senior attorneys. The internal complaint described an on-duty Action K9 team handling a dog that appeared entirely unfit for service, noting that despite wearing a muzzle, the animal repeatedly growled, lunged, and barked aggressively at commuters passing by.
The scope of commuter complaints extended well beyond the behavior of the canines. The records documented numerous allegations of guard misconduct and operational neglect, ranging from security personnel failing to perform basic duties to active harassment of passengers, including reports of guards catcalling women on transit platforms.
The documents also provided insight into the agency's internal handling of serious security failures. Complaints submitted regarding the violent July 2025 Red Line brawl were marked as officially closed within approximately 24 hours of receipt, with the records offering no evidence that a comprehensive investigation had taken place.
Both the CTA and Action K9 Security declined requests for on-camera interviews regarding the findings. However, Action K9 asserted in an emailed statement that various released complaints had been incorrectly attributed to their firm instead of other private security vendors. The company maintained that any allegations properly associated with its staff were found to be completely unsubstantiated following thorough internal investigations.
For its part, the CTA maintained that it acts promptly to investigate all incoming passenger complaints. Nonetheless, the protracted legal fight and the subsequent revelations continue to fuel debate over the transparency of the transit network and the effectiveness of relying on costly private security firms to safeguard public transit infrastructure.
