There are already plenty of laws which should deal with this problem, but they are not being utilised - shops selling to minors, people buying alcohol for those who are under age, publicans/club owners selling to people who are already drunk, light sentences for those causing damage or driving while under the influence..
What shocks (or perhaps surprises me) is how much money young people, and children, seem to have these days. I reckon even putting a minimum price of £3.70 on a bottle or wine will not stop them being able to afford it to excess.
I gave up buying our local paper a couple of years ago because the court reports were so unutterably depressing. The whole page was taken up with cases of damage and assault caused by people who were roaring drunk at the time, drunk people abusing ambulance and other NHS staff.
I was out and about at a really early hour on a Saturday morning several weeks ago, obviously before the council cleanup vans had done their rounds, and was having to dodge piles of vomit and piss on the pavements.
This is not a new problem in Scotland - there is a history of the population, especially the men, drinking to excess. BUT, previously, there was also a sense of shame within families if the drunks were abusive/dangerous/violent. This appalling behaviour now seems to be almost honourable amongst certain sections of the population.
I have no idea how the issue can be tackled successfully.
