Can't see the video anymore. From what I saw I didn't see anything that resembles the usual methods of cheating. Stuff like that happens all the time, it might look like he killed him in one burst but without seeing what's happening on the other players end then its impossible to tell. I've been sniped untold times when I know that I've got back into cover before they've fired, but all they need is a second of lag and bam. Not saying this guy doesn't have a dodgy connection, it might even be on purpose, but its impossible to tell so you can't really call it cheating.
