http://www.nbcwashington.com/news/local/DC_Chief_Expects_One_of_Largest_Crowds_Ever_for_Inauguration.htmlThe District is expecting one of the largest crowds ever for president-elect Barack Obama's inauguration on Jan. 20, Police Chief Cathy Lanier said.
Many more streets will be closed to traffic downtown compared to prior inaugurations, she said.
Lanier urged people "to use really good common sense" in making plans, and highly suggested that those headed to the event not drive.
About 3,000 police officers from across the region help patrol the event, but Lanier said there will be at least 4,000 this time from about 100 different police departments.
Former D.C. police chief Charles Ramsey, now the head of police in Philadelphia, has already offered Lanier support from his city.
Lanier said the security perimeter around the inauguration will be much larger than in past years, and rolling street closures may be needed. Officials are still making decisions with the Secret Service on details.
