We've chronicled photographer harassment in the D.C. area, most recently at Union Station, where amateur photogs have encountered great confusion as to who owns which portions of the station and shops, where those sections end, and what rules apply to photographers in each one. Tomorrow, the Subcommittee on Economic Development, Public Buildings, and Emergency Managment of the U.S. House of Representatives, chaired by D.C. Delegate Eleanor Holmes Norton, will try to find answers to those questions in a hearing at 10 a.m. Representatives from the Union Station companies will testify, as well as the Director of D.C.'s Department of Transportation, and notably, one of our Flickr contributors who has pursued this issue relentlessly, Erin McCann (PDF). The hearing will be webcast live; you can also catch a report afterward by Flickr user LightboxDC, who will be in attendance.
