There are three extremely messed up things going on here.
1. A woman rammed her husband's car with her own vehicle in a school parking lot.
2. She did it because she thought he was going there to pick up their son from school.
3. She did it because she thought the child WAS ALREADY IN HER HUSBAND'S VEHICLE and tried to ram it in order disable it.
Thank the powers that be that the child was not actually in the vehicle, but he was standing nearby and witnessed it.
How exactly do you tell a child that "Mommy hit daddy's car because she was trying to stop you from leaving."?
