I just watched a program about the recent terrorist attack on a Nairobi shopping mall.
Al-Shabab terror attack in Nairobi shopping district angers Kenyans - Washington Times
The mall has very good surveillance cameras, sharp pictures instead of the blurred ones we often see. Several times the terrorists fired their AKs and long streaks could be seen extending from the barrels to the picture's edges. I have seen .22 bullets when the sun was exactly right and once saw a .44 bullet in flight, but these are rare occurrences. In the videos, nearly all the streaks were visible. I am guessing that the images imprinted on the CCD pixels and remained there for at least one scan, possible more, which would mean they would be on screen for at least 1/70 second.
Has anyone else seen this effect?
