Why isn't Wal*Mart (or more properly their insurance company) going directly after the trucking company for compensation? As I understand Subrogation that's how it's supposed to work -- the insurance company sues the trucking company on behalf of Ms. Shank to recover money they spent on her medical bills.

It seems like any additional money Ms. Shank wins herself from the trucking company for negligence, pain and suffering, and stuff beyond the scope of what the insurance covers should be hers to keep.

Seems like some details are missing from this popular press article...
