Based on the police report, the prosecutor has no credible legal basis to file a criminal complaint (charging document).
The
fact that EE was not arrested, witness statements - all of which support EE's statements to the police, in conjunction with denial by EE, & the lack of criminal history by EE, all point to a unsuccessful outcome for the prosecutor and not guilty verdict if the case went to trial.
Prosecutorial discretion would clearly err on the side no to file charges.
Even the most zealous prosecutor would not present this case.
On the other hand, Goodell & his cronies can conduct their own investigation and even suspend a player, notwithstanding the fact that the player has not been charged by the authorities.
One of the outcomes of the Ray Rice fiasco, NFLPA & NFL agreed that the NFL disciplinary policy is not ultimately determined by the lack of official criminal charges being filed.
Even so, with a full NFL investigation, can't see Goodell suspending EE based on the facts (no history of documented violence, etc.).
But if EE interviews with the NFL act contrite, innocent, and regretful that bad publicity/PR has been inflicted upon the NFL (being that the NFL is really concerned about the brand name and the NFL "shield" in the eyes of the public).
