I also blame the manufacturer of the safe because the safe was not as secure as they claimed and because it's not like securing things correctly is an unsolved problem or even just np-hard.
information can be stolen more than once, and if it can be stolen by these people, then you can damn well bet that it can be stolen by people who might not want to let you know that they took the information. how long has that data been sitting there unsecured? how many times has that data been stolen through unauthorized access? is it even reasonable to ask to be able to run a pen test against anyone who wants my information, so that i can actually know my data is secure?
