if there is a collision or near collision at an FAA ATC airport...it is almost always an ATC error.
Bubbers was on his toes ( Litteraly )...and all pilots must be on the lookout for ATC errors that might put the pilots in danger.
Always a WHAT IF must be in your mind...WHAT IF ATC tells someone to go around and they don't? Do you want to measure professionalism at that instant...or can you imagine the controller making a radio call while the plane intended to receive the call might be transmitting and blocking the go around call?
be careful out there...ATC screwups can kill you.
