"Law enforcement is not tracking any specific or credible threats to the inauguration, according to outgoing FBI Director Christopher Wray. About 25,000 law enforcement and military personnel will secure the inauguration attended by several prominent leaders and 250,000 guests, as stated by the U.S. Secret Service. The inauguration has been designated as a national special security event by the Department of Homeland Security, which includes extensive security measures. Attendees should expect to see drones and tactical teams on rooftops, as mentioned by Matt McCool, U.S. Special Agent in Charge of the Secret Service Washington Field Office."
