Years ago the Pupil Council at Park Lane Primary School asked if there could be lessons about 'scams'. They reported that their parents, particularly those not yet fluent in English, had been tricked. They went on to discuss 'legal' scams such as those where computer printers were sold cheap only for the customer to discover that replacement ink was extremely expensive and cartridges machine specific. Now of course some printers have software that prevents cheaper compatible cartridges being used.
The variety of scams has increased since then so the publication of 'The Little Book of Big Scams' published by the Metropolitan Police and the Mayor's Office is very welcome.
My only criticism would be that it is very wordy and so may not be accessible to the parents children spoke. I am not sure if it is available in languages other than English - a video version would also be useful.
