I thought of that too.

If she'd even mentioned it when the police arrived, it would have been more credible.
But she waited until she had spoken to her attorney, and then, conveniently stacking up evidence for her case retroactively, only mentioned it then.

If there really was a choking incident a week or so before, she would have gotten away from Zimmerman then, and immediately called the cops right after to have them supervise Zimmerman move out of the residence with his possessions. She wouldn't have stuck around waiting for the inevitable next incident.
