The overlap with criminal justice and cybercrime is the crimes that take place. Cybercrime refers to criminal activities that are committed using digital technologies, such as computers, networks, and the internet. While criminal justice are the crimes people do in real life not over a computer. The thing about cyber crimes is that people typically try to do them more because they figure it is not easy to get caught. You can a persons identity both online in person, it would be easier to do it through a computer simple because someone would have to deep dive for evidence that traces back to a certain individual. That can be done but it take lots of time considering the fact the individual dong the crime can be extremely smart and know how to work well with computers. Child porngraphy is another, a predator over a computer screen can easily manipulate a child into sending them nude photos by pretending to be someone they are really not. Which a predator can do in person while having control over a childs mind. I guarantee if you can complete the crime in person you more than likely can do so over a computer screen.
