As much as I dislike the behavior, ARRESTED? I assure you that I am assaulted daily with what I consider unacceptable behavior from a great variety of people. But I don’t call the police.
Telling the kids he’d lock them in a hot car? Big deal.
Would it have been menacing if he just told her to “Get Lost”?
Arresting someone for foul language is a VERY slippery slope.
