3 steps to public humiliation

1. a little girl draws a picture of a gun
2. her teacher shows it to principal; principal calls in the police
3. her father, arriving at the school to pick up his children, is arrested

          IN FRONT OF THE SCHOOL

now, the police and the school can talk the good talk of firearms safety, concern for the child's welfare, and their duty to report the drawing...

but is arresting an innocent-before-proven-guilty father in front of his children's school community necessary to the child's welfare? 

can they seriously argue the threat of violence was so high at that time, they had to act immediately?
no.
it was to humiliate him.
plain and simple

then the strip search at the station.
and showing up at his home to tell his wife:

1. he had been arrested
2. they had to search the house
3. they had to remove his remaining children into care

and all this done without telling the woman what her husband had been charged with.

so maybe the school and police were hoping for a further humilation by causing his wife to doubt her commitment to him
