well... living in a country that does not even consider a businness paying you if you fall and fracture or whatnot in their sidewalk...

I would say the person should pay... I mean she (assuming she´s a she) was the one who fell.... if I fell I don´t blame anyone but me.. LOL... adn usually laugh it up...

IF.... IF.... out of 10 people passing by 8 or 9 or even 10 stumbled or fell I would consider making a reposrt so the sidewalk got fixed...

just like in school if a student flunks who´s the fault??.. the teacher or the student?... IF ALL students flunk who´s to blame??......

Medical bills might be expensive but one should learn to look where you are going and if you have an accident then be it...it could´ve happened anywhere... so why should others pay for our "stumbles"... unless as I said it where a situation where most of the people had suffered from teh conditions of the sidewalk... but even then I think the city is the one that should fix that..
