FORBES: Relatives of firefighters killed at the World Trade Center in 2001 reproached Republican presidential hopeful Rudy Giuliani in a video Wednesday, pairing footage of the falling twin towers with charges that the city’s former mayor was woefully unprepared for Sept. 11, causing needless firefighter deaths. The parents and siblings of some of the 343 firefighters killed in the terrorist attacks released the video with the International Association of Fire Fighters, which opposes Giuliani’s candidacy.
