Making Light:  Bruce Schneier on Rachel Maddow ::: December 29, 2009, 09:32 AM

Washington, D.C.'s subway system lost its litter bins shortly after
9/11, but redesigned bins were installed thereafter.  I don't know
how the new ones are supposed to be safer than the old ones.  But I'd
rather not ask searching security questions, lest someone decide they
aren't that safe after all and take them away again.
