What technology is necessary to gather that much video so quickly? Is that video feeding into a central hub? This is Dubai, a relatively tiny country. Did they build this technology themselves or did they license it. The technology is CCTV http://en.wikipedia.org/wiki/Closed-circuit_television http://en.wikipedia.org/wiki/Closed-circuit_television. It is imported from all over the place and is probably not feeding into a central hub. In most countries UAE included it is found in all hotels, airports and Shopping Centers. The assassins for sure knew about it but because of their modus operandi did not worry about it. If you notice the end of the video says the hotel staff opened the room 17 hours later and that the latch was locked from the inside. They made the murder appear as a heart attack (other reports at the time) reported it as electrocution - probably killed him by inducing a heart attack via electrocution. The team scattered to different places and all the names and nationalities mentioned are probably false. They also probably had multiple passports and on leaving Dubai appeared in another country with a different name.
