So I just saw the AEW segment regarding the footage for the brawl at their All In event.
I rewatched it a few times and it looks like Punk instigated physical contact first. However an interesting tidbit I just noticed was that Tony Khan was on the right side of the screen (behind the monitors).
As the scuffle occurred, it looked like they hit the monitors/almost knocked over the monitors, but Tony (as he was sitting down) quickly tried to hold the monitors in place then stuck his hand out during the scuffle.
Once Punk and Perry were separated, it looked like Punk angrily went around the table and lunged at Tony, but was pulled away.
What Tony Khan said has some more validity now and I can understand why he felt unsafe and why he had aired the footage in response to Punk's recent interview.
Maybe I am missing something, but I cannot believe people were cheering for Punk live at the event. I get that he was upset with Perry, but it's clear that Punk acted unprofessionally for starting the fight and then angrily lunging at his boss.
