Well, I didn't see anything wrong and have to agree with Ommadawn on this one for now.
The reason you see the bullets curving is because the distance ping which is 60 in your case.
It happens when you record someone moving fast and ping is also taking place here even though it's only 60.
if you really want to catch him watch him playing vs michaeljordan (same ping, they have no distance against each other) and then you can see clearly his perspective.

My final say is a no (for now), waiting for more opinion, in meanwhile you can keep posting moments where you find the user super suspecious.
