This isn't Wal Mart's first rodeo. I would think that they have some kind of procedure in place for these type of days. I'm guessing that that particular store did not follow proper procedure. Otherwise, Wal Mart is lucky it hasn't occured elsewhere. I would guess that even if Wal Mart had a procedure in place to prevent this and if this store did not follow that procedure, Wal Mart might still have some liability here. Perhaps not as much as if they didn't have a proper procedure in place but the victims aren't going to get a lot from the store manager.
