"Just what would be classed as drunk, just more than driving limit, just under driving limit, or the same as me the other week when I had 2 pints and tripped over a loose kerbing"
Clearly you have not visited the A & E department of many inner city hospitals. There are people who are completely drunk and abusive - not the people you describe- there is a really obvious difference. This type of self abuse is different from the other issues that FE raises. That is why I think they should be warned that "one strike and you will be charged" is perfectly reasonable - or that they sign up to a course to wean them off, if dependant on alcohol. These people who are seen on the streets totally out of control on a regular basis are in a different category and should be treated as such. In some countries they are indeed charged, so why not here?
