This article by John Whitehead is profoundly disturbing.
That young children are being increasingly subjected to police violence and military hardware is heartbreaking.
Fortunately he quotes an example of where a school was taken over by new management determined to use non-violent methods and pupil empowerment. The police were not pleased but they carried on and after a year the drop in serious incidents was down by a staggering 90%.
Just goes to show.
What sort of world do we want?
Then start by reflecting this in how we treat our young children.
