It's all just a smoke screen. They don't actually expect the laws themselves to change much. The idea is to get the notion into the public consciousness that there is a problem and the government is dealing with it.
The problem is cheap alcohol so the solution is to raise the price. Talk about it now so people don't get too upset when they load on the duty in the budget.
It's about tax revenue but I think they are actually being very stupid, even from a revenue point of view, as more tax on alcohol will simply increase the number of cross border trips and people will not restrict themselves to buying alcohol when they are there.
It's time to move up north, I think. The economy there is set for a boom time thanks to Fianna Fáil.
