I see both the government and the next government are presenting plans to deal with the evil of alcohol. While there are health issues associated with alcohol and drunks can put themselves into risky situations these dangers by and large are by and large borne by the drinkers themselves, there are exceptions to this, such as drink driving but they can be dealt with separately. The reason that it is a problem for society at large is because of the antisocial behaviour of people getting drunk in public and becoming aggressive and obnoxious towards other people.
However most people don't behave like that whilst intoxicated, in most countries the scenes observed in British town centres every Friday night are not the norm. Alcohol itself does not make someone violent. Studies* have in fact shown that people become violent and agressive whilst drunk have very particular personality traits whilst sober- they tend to be those who blame their misfortunes on external forces rather than taking responsibility themselves, thus being drunk becomes an excuse to behave badly.
If anti-drinking campaigns emphasise the role of alcohol in turning people into antisocial yobs it could actually reinforce that behaviour by encouraging them to attribute the harm they to to the drink rather than to their own decisions.
* I'll dig up a reference later.
