In light of the recent discovery of cocaine inside the West Wing of the White House, I am wondering if a person who either lives in, or works in, or makes a visit to the White House, is caught using an illegal drug within the White House by a member of the Secret Service, whether that Secret Service member can immediately arrest that person and then turn that person over the Washington D.C. police department for prosecution.
Or, is arresting someone in the White House for drug possession/drug use not one of the job duties of the Secret Service?
Can the Secret Service arrest someone who uses an illegal drug inside of the White House?
