Justiciar,
You make a good point: how could it be dealt with better? Probably, it couldn't be. The system works, but society has changed a lot and is more querulous than it used to be.
The point is that a reflex these days is to sue a professional if anything goes wrong: what the hell, you might get something, so give it a go!
Liability insurance for medics in Europe is a tiny fraction of what it is here. People have a different attitude to life and they don't always think someone is to blame.
Personally, I don't like the way British society is going in so many aspects and this is just one of them, but quite symptomatic of the whole.
