First off, I'm from Australia, so my experience and knowledge may not translate directly (I'm assuming you're in the US).
What you need to do is look at the career as a whole and identify the roles that are suitable - just like you did checking out dispatching. Wasn't your thing, that's cool, still other options.
My first suggestion would be law, but you've ruled that out. Could you elaborate a little more on why you can't stand the legal field? There's quite a lot to it and you might find an area that does interest you - although it might take you away from criminal justice.
The area in criminal justice that I haven't seen anyone mention here yet that might interest you, and I believe is accessible, is criminal intelligence. The various state police departments in Australia, as well as the Australian Federal Police, all have intelligence sections. The roles are civilian (possibly a mix of civilian and sworn, I'm not 100%) and examine data, trends, evidence etc to assist in crime prevention. My understanding is they tend to focus on organized or serial crime.
At the federal level you'll also have another set of opportunities with the intelligence units that people are more familiar with. In the US that would be the CIA and NSA, here in Australia we have organisations like ASIO and DSD. Intelligence roles in these organisations are looking at threats to national security (which could include anything from terrorism to smuggling rings), but also cover battlefield intelligence (I'm not sure the set up in the US, but that's what DSD covers in Australia).
Then you've also got the options in the private sector, particularly around cybercrime. Police departments, national intelligence agencies, and defence also run cybercrime/cyberintelligence units, but I suspect the private sector has more of an investment in this type of intelligence than any other.
So I'd encourage you to consider that aspect of criminal justice. If you'd like to know any more, I can answer questions as best I can.
Oh, and I'm a paper pushing bureaucrat. I work in a state government department coordinating our Parliamentary Briefing Notes (things Minister reads in Parliament when asked questions). A lot of a reading and writing, a head for politics is very usful (I'm as close to the political frontline as a public servant gets basically).
$1Best of luck.
