No replies from the U.S. Capitol Police but as none of us have tickets their list is probably a moot point anyway.
The
Secret Services Inaugural website makes the following statement:
Quote: Security Screenings: All attendees are subject to a thorough security screening before entering the Inaugural parade route, the White House reviewing stand or the Inaugural balls. Please allow for additional time for this security screening, as it is expected that lines may be long.
Prohibited Items: As a security precaution, the following items will be prohibited from Inaugural parade route, the White House reviewing stand or the Inaugural balls: firearms, ammunition, explosives, weapons of any kind, aerosols, supports for signs and placards, packages, coolers, thermal or glass containers, backpacks, bags exceeding size restrictions (8"x6"x4"), laser pointers, animals other than helper/guide dogs, structures, bicycles and any other items determined to be a potential safety hazard. With respect to signs and placards, items should be made of cardboard, poster board or cloth and have dimensions no greater than three (3) feet in width, 20 feet in length and one-quarter (1/4) inch in thickness. Surrendered items will not be returned, nor available for pick-up.
So far I have not found any descriptions of security procedures, if any, on the public area of The Mall. The
National Park Service Inaugural website is very sketchy at this point.
The National Park Police are mum on the issue...
Details as I dig them up...
