Where to begin with this...
1.) Fine, the one video with the Jets catching them was shown, but every other video as well as folders on teams / DCs hand signals going back to 2000 were destroyed. Now why would the NFL do that?
2.) False. Teams are not allowed to: "Use at any time, from the start to the finish of any game in which a club is a participant, any communications or information gathering equipment... including without limitation videotape machines, telephone tapping or bugging devices, or any other form of electronic devices that might aid a team during the playing of a game.” BB chose to interpret this rule as being allowed to tape from the sideline if you didn’t use it in that same game - which the rule clearly doesn’t say, but is a convenient interpretation for someone trying to cheat.
If that wasn’t clear enough, the NFL Game Operations Manual says: “No video recording devices of any kind are permitted to be in use in the coaches' booth, on the field, or in the locker room during the game.” Couldn’t be more straightforward. The 2006 memo you reference was not a new rule and instead was meant to clarify these existing rules as it related to taping signals.
Perhaps you could argue that taping signals from the press box was just unethical but not explicitly prohibited until the 2006 memo, but that’s not what they did. Instead they taped from the field, which was clearly prohibited - and went to great lengths and risk to disguise the cameramen in order to do so. It must’ve really been worth doing to go through all that trouble. Unlike Deflategate, they also didn’t protest the penalties, which is also very telling. Case closed - they knowingly cheated. Not to mention all the other allegations.
3.). Irrelevant.
