In this case, I think a lawsuit is deserved. If that was my wife that got killed I'd be mad as hell. It's not like there was a tornado and it was an "Act of God". In my very simple mind I would think that the sign contractor is liable, but I'm thinking that TB may have some liability too. Should TB be responsible as it is their property, both the parking lot and the sign? Maybe it will be argued that since they were doing business there and not with TB that they are not responsible?
