Most of his kills are questionable with the distance, speed of acquisition and near snapping of targets, but these stood out the most to me.
Time: 1:09
Reason: watch the kill of the guy behind the desk. He tracks their movement before any indication of them being there.
Time: 2:02

Reason: Snaps to enemy not only off screen but above him instantly.
Time: 7:03
Reason: Tracks player through a wall with no visible indication of their presence.
