Wolf was arrested on the spot, in front of her husband and children in the middle of a grocery store, and charged with disorderly conduct. The humiliation of that moment was likely far more damaging to Wolf and her family then her swearing at her husband in front of her kids was.
I don't know why people feel they have the right to police others all the time. This is horrible.
In Spain, if you called the cops for something as ridiculous as this, you'd get fined.
