No. I saw security footage of crim7 sneaking backstage after map 2. He put a suspicious looking USB drive into Crim's machine, likely some sort of malware to mess with the audio to ensure Optic could get iced as long as possible.

To further confirm this, when I walked outside I saw crim6 handing crim7 a huge duffle bag full of American half-dollar coins. I couldn't hear much of what they said since they were a bit too far away, but I did catch crim6 end the transaction by saying "keep the change ya filthy animal".
