Horrible stats and did this http://battlelog.battlefield.com/bf4/battlereport/show/1/948427156146204096/1539680512/

As I watched him on the server stats page I saw all the headshots before I banned him

As you can see from the multiple headshot kills in just a few seconds time he is bs especially in comparison to his overall stats.  He is simply toying around with is aimbot.  Look back in his battlelog stats and you can see when he started doing it.
