Around here the police employ underage teenagers to go and buy fags and drink from shops and stores and then follow up in a fine then they name and shame them in the local paper,
BUT , they always manage to get more from another shop or get someone older to get it next time,
Our police have also starterd stopping kids walking about and if they have any drink with them ,, even if it is in a juice bottle they don't hang around they make the kids pour it out down a drain then walk them to a bucket to put the empty bottle in, and if they refuse they get escorted back to the station
