The stun/flash stuff I can generally explain away with obvious code faults concerning elevation and whatnot. But smoke doesn't work like that. On the killcam there is no smoke at all, and they easily shoot me when I can't even see them. That is why I started to wonder if smoke grenades worked like flash in that if your team throws it, you can see through it. But now that I think about it, I know that isn't true. So it makes me wonder if maybe it's possible someone is cheating. I mean it could be a bug, but it's an odd bug.
