Bad Things Happen

I know next to nothing about civil law, but it is my understanding (and certainly that of very many people) that it is safer from a legal point of view not to make any attempt to clear snow and ice, because if you do it less than perfectly you may be liable for injuries to others, whereas leaving your path or car park or whatever covered in untouched snow and ice leaves you bulletproof. This has to be bad law; the sum total of accidents and injuries will be higher with snow left uncleared than if efforts are made to have a go at it, even imperfect ones.
When I am elected as an MP by acclamation my first Bill will be the Bad Things Happen Even To Nice People Bill, short title "Shit Happens - Live With It".
Don't hold your breath.
