Im not talking crime either. The nfl don't have leeway to switch from no punishment to punishment on something they already said it was no punishment for. Don't know where you got that from.
As far as different no its not. If I grab some random girls butt and she reports me would I get in trouble or not? If the answer is yes how different is it?
It's all about how the NFL views it, not you or I.
For example, let's say a player grabs a woman's butt out in public. Even if it's not a woman he knows, the NFL wouldn't likely do anything about it. However, let's say he's a chronic butt grabber and does is dozens of times over a period of time. The NFL would be more inclined to do something about that.
What everyone has to remember is what I have pointed out several times .. the basis for the NFL to act is "conduct detrimental to the league". That is a VERY subjective rule that can be applied from different angles.
For example, they could say "exposing a woman's breast in public is illegal in 3 states who consider it sexual assault so we are justified in calling it that." They could also go with a completely different angle and say, "An NFL player damaged the NFL brand by exposure a woman's breasts to children in the crowd and throughout the world who have seen the video."
As I said, there are many ways for the NFL to justify re-opening the case. I am not saying the should.
