Using official police logos, such as Danish police or other European law enforcement logos, on your FiveM server can potentially violate intellectual property laws, even if the agency is state-run rather than a private company. Many countries, including those in Europe, have restrictions on the use of their government agency logos, including law enforcement symbols, as these are often protected under specific regulations or trademark laws.
For FiveM, it is generally best to avoid using real-world logos, as they could bring legal complications if the intellectual property holder (in this case, the police agency) objects. This might not be directly against FiveM’s terms of service, but it could lead to problems if the respective country’s police or legal body takes issue with the use of their logos. Instead, many servers opt to create fictional logos inspired by real-world ones to avoid any legal concerns.
