This, in my opinion, seems clean. I'm basing my judgement on the demos evidence.
I will say, however, the shots from long A down in to CT spawn were a little suspicious. After he kills the CT who's just knifed a Terror in CT spawn, he then has insta-reactions on more CT's arriving in CT spawn.
He's in the same situation a few moments later when no CT's are in CT spawn (but couldn't obviously know that) and he behaves very differently. Which is in contrast to the behavior previous when there were CT's approaching (but couldn't know that either). Surely if he played legit he wouldn't insta-scope and shoot a CT in one instance (when CT's are down there) and then casually walk out along long-A when there aren't.
But that's all I've got really.
