Hello!
This occured to me twice. I mostly play Hunter mode. In Williamsburg (as CELL soldier) I often use hideaway in the building shown on first screenshot. No rain, no wind, no proximity alarm, EMP grenade in hand - ease... . Suddenly - I'm dead... Killcam following. My killer is staying as it's shown on first screenshot. Shooting normal arrow which probably comes through the wall and killing me...
So I told to myself that the wall is very thin and arrow can go through. I've tried. As you can see on screenshot no.2 arrow can't go through.
Is it bug, cheat or what? I don't think it is ping issue. It happened to me in different times on different servers with ping about 60.

The other guy could've had a high ping if you were at the window and moved away into the corner before dying

I was "sitting duck" for a long time.
It happened to me many times that my arrow in killcam went through moulding or frame of the window or corner of the wall although I saw it's been in realtime OK (I dunno how to cheat). In this case arrow comes through middle of the wall far away from the window.
In a fact - one of this "miraculous" shooters I've asked immediately about his hypotetical cheating and I didn't receive answer. Player suddenly evaporated...
BTW, sry for my poor english
