Hypothetical,
1: say a father wanted to take back is child..
2: say a stranger wanted to abduct a child..
3: say an innocent man wanted to save a life..
and the car driver gets into a fight with that person
Then tells the police "that that person is trying to steal your child, regaurdless if it was ever in the car or not"
As the long as you have a smashed window.. its legal
