Maryland, USA — 2014. What started as a quiet night of blackjack for Justin Mills at the Maryland Live Casino quickly escalated into a physical confrontation, a constitutional dispute, and ultimately, a federal lawsuit. Mills’s refusal to present identification to casino staff led to him being physically restrained, threatened with arrest by off-duty police officers, and permanently banned from the property. His decision to take legal action would not only vindicate his rights but also spark discussions about the boundaries of private security authority and police power in the United States.
An Ordinary Night Turns Unusual

On a warm summer evening in 2014, Justin Mills, a well-experienced blackjack player, entered Maryland Live Casino in Hanover, Anne Arundel County. Known for his strategic approach to gambling, Mills employed card counting techniques to increase his chances of winning.
While card counting is often frowned upon by casinos, it is not illegal under Maryland state law. Casinos may refuse service to players they suspect of card counting, but they cannot detain, search, or forcibly identify individuals without a legal basis. Despite this, casino staff closely monitored Mills’s gameplay, noting patterns that suggested he might be counting cards.
Throughout the evening, Mills won several hands, drawing the attention of casino management. Surveillance footage and floor managers flagged his play as “suspicious,” leading to repeated interventions. However, at no point did Mills cheat, manipulate cards, or commit any illegal act.
The Physical Detention

As Mills attempted to leave the casino, a team of security guards intercepted him. According to Mills’s testimony, the guards grabbed his arm and twisted it behind his back, forcibly escorting him to a private security office.
Inside the office, casino personnel demanded that Mills provide identification. Mills refused, citing his legal rights. Despite repeated requests, he maintained that he had done nothing illegal and was free to leave.
Escalating the matter, the casino called in two uniformed police officers who were technically off-duty but present in their official uniforms for secondary employment — a common practice allowing casinos to hire police officers part-time for security purposes. Crucially, while in uniform, these officers were acting as private employees of the casino, not as representatives of the state.
Police Involvement and Threats of Arrest
When the officers arrived, they immediately sided with casino security. They informed Mills that refusal to present identification would result in arrest and fingerprinting. Mills, aware of his rights, continued to refuse.
Maryland is not a “stop and identify” state. This means individuals cannot be compelled to provide identification unless lawfully detained on suspicion of a crime. Since card counting is legal and Mills had not committed any crime, he was under no legal obligation to comply.
Feeling threatened, Mills eventually produced his passport to document the encounter, after which casino staff issued a seven-day ban. Soon after, he was permanently barred from the casino, marking the beginning of a legal battle that would question the limits of authority for both private security and police officers.
Legal Framework and Civil Rights Analysis
Mills decided to file a federal lawsuit against Maryland Live Casino, the security personnel, and the off-duty officers. His claims included:
- False imprisonment — being physically detained without legal justification.
- Violation of civil liberties — asserting his Fourth Amendment rights against unreasonable seizure and detention.
- Abuse of authority — off-duty officers acting as casino employees exceeded their legal authority.
The case drew attention from legal experts and civil liberties organizations. Lawyers emphasized that while casinos have wide discretion to manage their properties, they cannot impersonate law enforcement powers to detain lawful patrons. Furthermore, the case highlighted a gap in understanding the rights of casino-goers in situations involving off-duty officers, whose dual roles often blur legal boundaries.
Court Proceedings and Outcome
The lawsuit proceeded in federal court. Evidence included:
- Surveillance footage of Mills’s detention.
- Witness testimony from Mills and casino employees.
- Legal analysis of Maryland stop-and-identify laws and Fourth Amendment protections.
The court ruled in favor of Mills, determining that:
- The casino’s actions amounted to unlawful detention.
- Off-duty police officers, while in uniform, cannot exercise governmental authority in a private capacity beyond legal limits.
- Mills was entitled to damages and legal remedies for the violation of his civil rights.
This case set an important precedent, clarifying the limitations of private security and the scope of off-duty officers’ authority when acting in a private capacity.
Impact on Public Awareness
Following the verdict, the case gained media attention, highlighting the rights of individuals in commercial spaces. Advocates for civil liberties praised Mills’s courage to challenge the casino, emphasizing that legal knowledge and calmness in high-pressure situations can protect personal freedoms.
Many casinos subsequently revised their security protocols to ensure employees and contracted officers understood the legal boundaries of detainment and identification demands.
Conclusion
Justin Mills’s encounter at Maryland Live Casino serves as a cautionary tale and a landmark legal example. It underscores the importance of:
- Knowing your civil rights.
- Understanding the legal distinctions between private security and law enforcement.
- The power of standing up against unlawful practices in a civil manner.
By challenging the casino’s actions, Mills not only defended his rights but also contributed to a broader dialogue about privacy, personal liberty, and the proper role of private security in public-facing businesses.
