- Darren Dixon as a father didn't do his job. If he had married JoJo's mother, JoJo might still be alive and might be in an in-tact home instead of the vulnerable home in which he lived. After all, homes without good fathers are vulnerable homes.
- JoJo's grandparents didn't do their job. JoJo's grandmother even knew that "was concerned his mother was planning to take him out of the country'", and she did nothing about it. Why didn't she call the UK's department of child protective services?
- The UK and the US governments didn't do their jobs to at least give JoJo's mother a chance to turn in herself to British authorities. If for no other reason than to let her turn in herself and bring home JoJo, take a plea deal and have prosecutorial immunity, and help the UK and the US fight against Daesh, the UK and the US should've let her surrender to the UK and US governments at the either the British and American embassies in Iraq or the the British and American consulates there. "CIA officials told their UK counterparts that a US Air Force Predator killed 50-year-old Jones in June as she tried to flee the group's stronghold in Raqqa," and "[i]n July a friend described Jones as being desperate to return to the UK, but she was apparently being forced to stay by her husband's comrades."
- Whoever continues to call Daesh "ISIS" or "ISIL" is not doing his or her job to not recognize a terror group as a state. When countries like Egypt are calling Daesh "Da'ish" (the Arabic equivalent of the name that Daesh absolutely hates) while the UK and the US somehow think that they're being as politically correct as one can be, I have to wonder where British and American exceptionalism went, by the way.
There are also others whom didn't and don't do their jobs. For example, where was L'Oreal in noticing when their employee was acting unusually, and where are individuals and other communities making sure that other single-parent homes and fatherless children aren't as vulnerable as JoJo's home and JoJo were?
