The bombing
You know they will have camera's filming the special precautions the police covering the event took, so I would imagine they got some great coverage of the police response. The military channel had two documentaries filming on 9/11. One following a crew going through USMC tank school, the 11th was their 1st day to fire the main gun. The other was a series filming recruits going through boot camp at Parris Island. Both shows had trainees from the New York area and did a pretty decent job recovering what those recruits were feeling.
Hopefully we can get some footage of the capture and or arrest of the A-HOLES that did this!
