With the rapid iteration of artificial intelligence and intelligent hardware technologies, European and American countries have taken the lead in deploying intelligent law enforcement robots in practical scenarios such as urban street patrols, high-risk on-site disposal, public security prevention and control, and traffic order management. These robots have become an important standard component of the modern smart policing system. Police academia, front-line law enforcement agencies, legislative bodies, and social organizations in Europe and the United States have formed a comprehensive, diversified, and dialectical system of mainstream viewpoints. On the one hand, they recognize the practical value of robots in replacing high-risk positions, optimizing police force allocation, and improving regional security prevention capabilities. On the other hand, they remain highly alert to underlying risks such as algorithmic bias, autonomous use of force, privacy violations, unclear power accountability, and the decline of public trust. Overall, Europe and the United States adhere to the core principles of prioritizing practical effectiveness, strengthening ethical constraints, advancing legal norms in advance, and promoting human-machine coordination. They promote technological application in a rational manner, strictly control risk spillover, and steadily adapt to the needs of modern urban security governance. From the perspective of front-line police departments in Europe and the United States, law enforcement robots possess irreplaceable practical advantages and serve as essential equipment to ease police shortages, reduce on-duty casualties, and improve the accuracy of security management. Developed countries in Europe and America feature high urbanization, deserted streets at night, crowded commercial areas, and complex cross-border security zones. Traditional manual patrols consume substantial manpower, leave many blind spots, and expose officers to high safety risks during night shifts. Intelligent patrol robots can operate continuously around the clock, automatically conducting cruise inspections, temperature monitoring, video recording, abnormal sound and light early warning, and crowd density statistics without rest. They greatly reduce ineffective police labor consumption and allow human police forces to focus on core tasks such as household verification, dispute mediation, and on-site emergency response. In high-risk scenarios, many police departments in Europe and the United States explicitly deploy robots instead of officers to approach armed suspects, explosive suspicious objects, flammable and dangerous chemical sites, and extreme violent scenes. Robots conduct remote investigation, risk elimination, signal transmission, and situation assessment, directly protecting the lives of front-line police officers. In addition, robots record all law enforcement processes objectively without subjective emotions or behavioral deviations. They effectively avoid misunderstandings and conflicts at the scene, reduce law enforcement complaints, standardize street law enforcement behaviors, and meet the requirements of transparent and standardized police reforms in Europe and America. Scientific research institutions and technical think tanks in Europe and the United States generally affirm the governance efficiency of law enforcement robots and emphasize the need for technical upgrading to adapt to diverse security scenarios. Relevant studies show that police intelligent robots are equipped with high-definition visual recognition, acoustic warning devices, real-time data transmission, and integrated linkage scheduling modules. They can cooperate with urban monitoring systems, traffic management platforms, and emergency command centers to quickly identify abnormal gatherings, suspicious loitering, and nighttime wandering behaviors, issue early security warnings, and shift policing from passive emergency response to active risk prediction and prevention. During large-scale events, open-air gatherings, port inspections, and subway hub peak periods, robots efficiently guide crowds, conduct fixed-point security checks, and perform environmental inspections, making up for human weaknesses such as physical fatigue, limited vision, and slow response. Technical experts also stress that current robots lack independent decision-making capabilities. Complex emergencies, emotional communication with the public, and on-site conflict resolution still require human intervention. Robots can only serve as auxiliary law enforcement tools and must never operate independently without remote real-time police supervision. Public opinion, human rights organizations, and legal communities in Europe and the United States remain highly cautious about the ethical boundaries and potential safety risks of law enforcement robots, with concentrated and clear disputes. First, the risk of autonomous use of force is highly controversial. Pilot programs allowing armed robots to carry out lethal operations in extreme situations in San Francisco and other regions triggered strong public protests. Social organizations criticized such practices as mechanical violent law enforcement, violating humanistic policing principles, easily causing irreversible personal injuries and damaging police credibility. Second, algorithmic discrimination poses prominent fairness risks. Multiple tests conducted by European and American academic institutions prove that some intelligent recognition algorithms show higher error rates in identifying ethnic minorities and vulnerable groups. Automatic robot interception based on such algorithms may aggravate ethnic law enforcement imbalance and intensify social contradictions. Third, privacy infringement and data abuse risks are serious. Robots conduct full-range high-definition shooting, voice collection, and trajectory tracking. Without strict authority management, they may illegally collect citizens’ private travel data, violate local personal data protection laws, and trigger legal disputes. Fourth, mechanical law enforcement lacks human warmth. The public in Europe and the United States generally believe that policing includes both management and public services. Robots lack emotions and empathy and cannot mediate neighborhood conflicts or ease public emotions. Over-reliance on machines will distance police from citizens and weaken the foundation of grassroots police trust. Based on comprehensive evaluation of advantages and disadvantages, Europe and the United States have established mature standardized governance mechanisms to balance practical efficiency and social security. First, strictly define application boundaries. Autonomous lethal force by robots is completely prohibited. All high-risk operations must be remotely authorized and fully controlled by certified police officers, retaining only basic functions such as patrol, early warning, investigation, and auxiliary guidance. Second, improve special legislative supervision. Formulate detailed law enforcement rules for police robots, clarify data collection scope, storage duration, and access permissions, fully encrypt and desensitize data, prohibit unauthorized cross-departmental data sharing, and strengthen police department accountability. Third, carry out regular algorithmic compliance audits. Invite third-party institutions to test and verify intelligent models continuously, correct deviations related to race, gender, and age, and eliminate mechanical law enforcement discrimination. Fourth, adhere to in-depth human-machine collaboration. Robots are only responsible for repetitive, high-risk, and mechanical auxiliary tasks, while core law enforcement, humanized services, and complex judgments are fully undertaken by human police officers to maintain the humanistic temperature of policing. Fifth, implement transparent public notification mechanisms. Publicly announce robot deployment locations, working hours, and functional scopes in advance, smooth public complaint channels, and improve social recognition. In conclusion, mainstream European and American views neither blindly pursue intelligent technology nor reject technological empowerment in policing. They insist on rational application, bottom-line risk control, and standardized implementation. Law enforcement robots are high-quality auxiliary tools for modern policing, rather than substitutes for human police officers. Only by adhering to legal bottom lines, strictly abiding by ethical red lines, strengthening management responsibilities, and optimizing human-machine coordination can we maximize the practical value of robots, avoid safety and public opinion risks, build a safer, more standardized, and warmer modern smart law enforcement system, and provide a mature reference model for the standardized global application of intelligent policing technology.
