I hope you didn't take any offense to my comments. Truly, I'm just trying to help. While I was not at the party, I have attended several in the past, and CMs were very diligent about checking bands. I have no doubt that you and others saw people without wristbands, however, unless you were present for both parades and all 4 stage shows, I find that the email would be taken more seriously if you used actual first hand experience versus what you assume happened.
Does anyone recall seeing those with the media lanyards wearing a wristband? If they were only issued lanyards, that may be part of what was witnessed. When sitting behind someone, it would be easy to notice the lack of a band, but a lanyard would be difficult to see from behind. Just a thought.
