The security for Donald Trump's 2025 inauguration involves a significant and complex arrangement, given the historical context and recent security challenges. Here's a breakdown of the security measures and considerations:

Security Measures: The Secret Service has been tasked with coordinating an extensive security detail for the event, which includes the involvement of various law enforcement agencies. This includes visible security like federal agents, police, and military members patrolling the area, as well as covert measures such as bomb detection systems, snipers, and radiation detectors. The U.S. Secret Service, FBI, Department of Homeland Security, and National Guard are among the agencies involved, with the Secret Service taking the lead in organizing the security for this National Special Security Event (NSSE). They have been preparing for this since the previous inauguration, with increased scrutiny and resources following recent security breaches and assassination attempts on Trump.
