Ah Jack, I'm glad I'm not the only one who found the video rather sinister. It seemed to be encouraging people to watch each other covertly and make dangerous judgements on their observations.
Thanks for the link; I'll look it up.

The video was somewhat wasted on my husband. His English (especially reading) isn't all that wonderful and he hadn't a clue what it was supposed to be about. The government actually paid him for the hour he had to spend, in company with other school cleaners, which I found rather strange. They never come across any pupils, as the school is shut when they arrive. Also, he's a Muslim himself, and felt a bit uneasy that people may be 'watching him' in case he tries to indoctrinate anybody!
