Mark O'Mara says that the dispute between George and Shellie Zimmerman at her father's house was the result of heightened emotions from their ongoing divorce.
O'Mara says there may be have been some "pushing and touching" but George Zimmerman never punched his father-in-law.
On the 911 call, Shellie Zimmerman says her husband had punched her father in the face and had threatened them with a firearm.
O'Mara says neither side wants to press charges.
Shellie Zimmerman said in her divorce filing that she and her husband had separated a month after he was acquitted in July of any crime for fatally shooting 17-year-old Trayvon Martin.
