I think everyone should agree to disagree without exchanging insults. We are all different people with different perceptions of the 'whys & wherefores' of this issue.
Having been convicted of drink driving myself, I know what a game changer it is to someone's life. Everyone's situation is different and I at least have sympathy with others who fall foul of the breathalyser.
In this particular case, we don't know if the neighbour has any other problems such as mental health or depression - he could be going through a very difficult time in his life. He shouldn't be judged too harshly because we don't know what is going on behind closed doors.
However, as FatMark has stated - do we actually know the neighbour IS drinking? Is there overwhelming evidence to support the drink driving? Putting two & two together to make five isn't enough.
If this is a genuine drink driver, like Grice96 has said it might stop the inevitable (a serious collision & loss of life) making that phone call. I know from my own experience, it stopped my own problems dead in their tracks when I was arrested, but it then created new ones (if that makes sense?).
On reflection it was the best course of action that I was arrested, because YES - I would have carried on drinking and driving if he hadn't have been caught on the 13th February 2019. Before, my arrest I became convinced that I could just keep getting away with it and never suffer the consequences. Maybe, this neighbour currently possesses the same attitude I had (if he is drinking and not guzzling cans of Roadstar). However, my own ban turned things around for me - the better I reckon.
There are no right or wrongs here, but ask yourself this - if this guy is genuinely drinking (if it is blatantly obvious!) and he kills a child, could you live with it on your conscious knowing you could have stepped in and done something to prevent it?
Food for thought. I'm not hear to ruffle anyone's feathers - everyone is entitled to their opinion, hence the whole point of the forum!
