New Lows for 60 Minutes

On 60 Minutes tonight Steve Kroft's story, GIs Lack Armor, Radios, Bullets, used video from Reuters TV. Kroft stated this video was shot a week ago and theres a date code of 20-10-2004. Kroft was basically using this video to show how dangerous it is for our under supplied troops in Iraq.

However, I think another story is being missed here. This video from Reuters TV has a perfectly framed picture of a road with an Improvised Explosive Device (IED) in the center of the frame. As US military vehicles pass, it explodes. This prompts a few questions.

1) How did Reuters obtain this tape?
2) If it was shot by a Reuters employee why was the camera set on a fixed position and centered on exactly where an IED was set?
3) If the Reuters employee knew the IED was there why did he film it instead of attempting to warn the military or stop vehicles from heading down this road?
4) Why did 60 Minutes air this footage without answering these obvious questions?
