Appropriate computer science dissertation?

I came across a guy with a bachelor's degree in computer science, JD, LLM, and PhD in computer science from CapTech. I saw his dissertation title and wondered if he should have been put in their PhD in Cyber Leadership program instead. This doesn't look like a computer science dissertation. It's more of a cyber law or criminal justice dissertation. He's now teaching at CapTech; CapTech hires many of its own graduates.



"Framework Proposal to Regulate Lawful Hacking within Criminal Investigations"

 

"Framework Proposal to Regulate [x] within Criminal Investigations" certainly points away from computer science.

But "Lawful Hacking" might point enough to computer science? Here's a 2014 scholarly article about lawful hacking. Although it's from a law review, its authors are all computer scientists (from Columbia, Penn, and a Guggenheim Fellow at the time).

 

It is not unusual for people to publish in journals outside of their field. Economists publish in criminal justice and education journals. I came across a group of computer scientists who are studying whether dogs can learn complex language skills. Certainly, some skills can apply to other fields, and other fields can have an impact on one's field. However, how is someone proving mastery of computer science and adding original knowledge to the field by doing a dissertation on law?

In addition, the PhD in computer science has no content coursework; it's entirely dissertation work. Since he's been working in the legal field and doesn't even have a master's degree related to computer science, he hasn't demonstrated that he's qualified to teach computer science at the college level. He's not currently teaching computer science; he's teaching cyber law, which he could have done with a cyber leadership, law, or protective services doctorate.
