Every now and then during the endless coverage we catch glimpses of firefighters from around the world paying tribute to our brothers and sisters who have fallen in this most terrible act. From the fireifhters in Colombia raising the US flag over their fire station in full turnouts, to the German firefighters staning fully bunkered out with their helmets over their herats, to the Hungarian firefighters who tied ribbons on their apparatus, and the Polish firefighters who sounded their sirens in tribute...these and many more acts we may never hear of show that this isn;t just a national brotherhood.....it's a worldwide brotherhood.
