The bottom line at least here in OZ, where we have the same ridiculous stupid risk assessment, simply put, is do not try unless you can be 120% successful.
It is all to do with money. Regretably those in power who make these decisions lose sight of the fact that the taxpayer is not in accord with their actions, after all they know what is best for you thats why you put them there?????????????????????????????????????????????
Commentators are correct in saying lawyers are suing and making money out of peoples misfortunes, but there are accidents, if they are not accidents then they must be intentional. That is not to say that there are not contributory influences by either party to an accident. The PC police have got in here as well.
The seat warmers are paid big bucks, not to run the respective Taxpayer funded service such as police, fire, etc, effectively for the publics welfare and benefit but to minimise litigation.
