my guess is that you are on the money. the police don’t like to get involved with family issues unless they feel there is no choice. my guess real young kids under the age of ten. a real dangerous road and a call into 911 by a concerned civilian. this is the type of thing where if IU was a cop responding I would try to give just a warning but if there were multiple calls over the year or the person became angry with the cop and escalated the encounter the cop would of felt he had no choice.
My Son in Law, a newly minted State Trooper read the article and said that if they were endangered on a state road he would have pulled her over and made her drive the kids to a safer road.
He then said that she probably mouthed off or did something else wrong.
Last night I had dinner with a friend who is in Emergency Management for a large city. He was telling about a woman who had called 911 500 times in the last year.
So those people exist. I would not their job for anything. A vast majority of people are nice. But that last two percent are real winners.
