Great, so yet again those of us who don't don't abuse 'the system' get penalised because of the idiots.
I knew when I posted this that someone would come up with this response, and I sympathise. In an ideal world we would not need police, speed limits, security checks, anti-virus scanners, and everything else.
Sadly the society we live in has moved away from punishing offenders to the extent that, as you say,
those of us who don't don't abuse 'the system' get penalised because of the idiots. Grossly unfair, but that's the way our so called 'civilised' society has evolved. I'm all for throwing these thugs out at 39,000 feet, but we all know that won't happen, so banning alcohol is a step towards maintaining a safer environment for the majority because of the actions of the minority.
Should we need to do it? No
Do we need to do it? Sadly I fear the answer is yes.
