Worth keeping an eye on

While the west lothian question remains unanswered, one of its towns, Armdale, is experimenting with a possible answer to underage on street drinking – raising the age of purchase in off licences to 21. The scheme has previously operated in Cleveland with significant success. Update I have been told that in Irvinestown the DPP got the local off licences to adopt different coloured bags to make it easier for police to identify the source. Should off-licences be required to have identifiable bags?
