alright, a few things i noticed.

1. there were definitely some fishy shots, i forget what gun he was on but it was right before the first time he got on the scout, i can totally see how he could know someone was about to come around the corner (his teammate died there recently), but he almost seems to prefire and gets a headshot (or 2 if i remember correctly)

2. galil kill. through a small gap, enemy was there for a split second and he nails him. not impossible, but either dumb luck or walls.

3. note when he doesn't move at the start of a round. i think i notice he plays slightly differently before and after those stoppages. (toggling?)

4. he shoots his teammate in the face with a usp at a time where anyone looking at their radar clearly wouldn't have done that. combine that with the supposed awareness he was playing with the rest of the time and it's a bit baffling.

overall, i'd say there's no HARD evidence (as is usually the case with walling accusations) however there are some VERY fishy moments in there.
