Being a Kiwi I see some rather ironic things here.
Firstly we are commenting on a set of circumstances we did not witness, we have only what the OP posted as evidence, and that evidence is not balanced by statements from other witnesses, which includes the camera owner, others at the table, other patrons, the woman.
Secondly, she did stop and aplogise, what else is she to do? Offer to buy a new one? To me she has behaved rather well in fact. Most of us get a bit flustered when we have an entirely surprising accident. Is she entirely at fault? I can not say, I did not see it. But from what is presented in this thread, I would say it would appear the camera placement was an accident waiting to happen.
Of course many outsiders see the USA justice system as being rather biased towards sueing for the slightest thing, you slip on icey steps and immediately look around for someone to sue, ie some one else to blame, and it seems to me that is the case here, a moments carelessness by the owner and now everyone is talking about sueing, except the actual owner of course. The lady took some responsibility for her part, and it could be that she took too much responsibility, I don't know, I was not there, surely the owner has to take responsibility for his/her gear also?
The camera should have been in a safe place, where it could not be knocked off, or snared by a hand bag or belt, or even bumped by coat tails in what is obviously an enclosed space.
Now look at the original post, the poster puts himself at the table, then says
Apparently a lady was walking past his table and her handbag caught on the 1Ds MK3's neck-strap
, so was he actually there or is he relating the tale third hand?
My first reading of the original post suggested a group at the table, after a shoot, all obviously photographers, yet none were watching the camera, if the had of been watching, the camera quite possibly could have been 'rescued' at the table before any damage was done.
To my mind the whole group is responsible, a group of photographers would normally look out for one another's gear and make the situation safer. Unless of course you are afraid of being sued for touching that which is not yours, even tho' you are taking it out of danger.
