Better more domestic surveillance than another Sept. 11, 2001, type of attack on U.S. soil? That was the question in a lively, sold-out, Oxford-style debate sponsored by The Rosenkranz Foundation at the Asia Society’s New York headquarters Wednesday night.

Hundreds of attendees paid $40 apiece to hear New York Times best-selling author David Frum, the Foundation for Defense of Democracies senior fellow Andrew C. McCarthy and UC Berkeley law professor John Yoo make 8-minute-long presentations in support of a proposition for more surveillance, while former U.S. Congressman Bob Barr, R.-Ga., George Washington University law professor Jeffrey Rosen and ACLU President Nadine Strossen opposed it. ABC News correspondent Chris Bury moderated.
