The bigger problem is society tendencies to call police for any problem.
Any mother who can’t hand her 7 year old has bigger problems.
I believe the policeman could have handled it better.
He should have told the girl not to approach the man. If she did, she would be arrested.
Police are being asked to handle problems they should not be asked to do in the first place.
They are in impossible situations many times. They are the canary in the coal mine detecting the sickness of our society.
