That's an interesting stat about the amount of murderers with alcohol in their systems. I'm sure if you could find stats for other things such as criminal damage, people cheating on their partners, petty theft etc you would also see some sort of correlation between them and alcohol consumption. The fact is that under the influence of alcohol you are just more likely to make bad decisions.

As for increased taxation of alcohol, here in the UK we already have to pay a lot in tax on our booze and it's not cheap! A lot of people still drink heavily, but younger generations are starting to drink less than their parents did
