That evening, after the majority of the population had returned home and Washington's streets lay empty, Chief Ramsey, his Executive Assistant Chief Terry Gainer, FBI Director Robert Mueller, and Secret Service Director Brian L. Stafford drove around D.C. to check security measures of the locked-down city. While several officers also wanted to assist with efforts in New York, many had to remain in D.C. and the majority of the department worked 12-hour shifts several weeks after the attacks. Ramsey noted that at the time many, himself included, thought that there were more attacks to come.
