This is my theory I know most of you will disagree, and thats ok.
Yesterday the SP contacted GZs attys and said We are not filing charges, but we want to talk to GZ to make sure that he is safe once the announcement is made. GZs lawyers call and leave a voicemail for GZ with the news, but instead of calling his lawyers, he calls SP. SP probably either tells him to leave the state, or offers some kind of protection.
Once he knows that he is not going to be charged, he calls Sean Hannity because he wants to present his side of the story and needs a show to go on. (Not going to go on NBC now is he?) Why else would anybody call the media??
GZs attys fire him because they were not part of the conversation with the SP, and understand that once GZ goes public they will no longer be in the spotlight.
The 72 hours is for police across the country to make preparations for the potential onslaught of riots. Also, it will get us to Friday placing the beginning of the riots over the weekend when businesses are less likely to be affected.
So I predict that sometime mid-friday the SP will announce no charges are supported by the evidence.
Once again, only my theory. Well know by Saturday if it is accurate or not.
