There are plenty of ways to break into the digital forensics field and the job market is still good in places like the DC metro area and consulting. The standard job search sites will illustrate what's open and what sort of background you need to get those jobs.
What is unrealistic is for people to think that a degree in digital forensics will act as a gateway into quickly working in a law enforcement forensics role. That's just not the way it works with law enforcement. There are civilian roles that you can obtain, but there is going to be significant competition. As I pointed out in that thread, there are a variety of federal law enforcement agencies that actively seek out those with technical backgrounds.
If you are passionate about digital forensics and get a proper education, there isn't anything to be depressed about. You just have to be realistic about how to start out your career. As you learn more and gain more experience, many more opportunities will open up.
My two cents I went to school (1 year in person, 3 years online) for Computer & Digital Forensics - did not have to take any programming courses. I have been in the field two years and still have not had to do any programming. I am also happy and feel I am doing something directly related to my degree. What I am saying is, it is possible to be in computer forensics without programming day in and day out. I promise. )
I guess after reading the rest of the posts I should also comment that I'm NOT in the law enforcement side of it currently - I am doing national security. I always wanted to focus on the law enforcement side but you should not rule out other options in Computer Forensics.. for one, security brings a lot more money and may not be as disturbing as the criminal law work. Do what makes you happy but don't turn away from seeing other options.. maybe start out where you can and then find what opportunities come out - computer forensics is far greater and includes far more than I thought it did when I first started school. There are many opportunities for someone with this degree/experience… and there is exciting work out there that doesn't just fall in the law enforcement category.
When I was working for LE and we were looking for staff (which was at least once a year over seven years) the only requirement for civilian staff was that they had a degree. However it did not matter what field the degree was in. We had people with Comp Sci, Electrical Engineering, Information Technology and even Business degrees. The point is that unless you are entering a protective profession that restricts entry through a professional association (think medicine, law or accounting) your undergraduate degree is simply a starting point. In order to get a job you are going to have to demonstrate that you have a strong interest in the field. This is not simply saying oh yeah that looks like an interesting job. It is taking the time to teach yourself in your own time, reading current papers and playing with the tools.
Our assessment process involved a 2 hour practical, but applicants were only given 1 hour to complete. We were looking at time management, decision making and initiative rather than 'forensic' knowledge. It is much easier to teach someone a process than it is to teach them to think. If you have a degree in digital forensics, but cannot figure out that a IDE cable does not get connected to a SATA hard drive I am not going to give you a job, no matter how good your marks were.
So for the original poster if I was you I would just finish your comp sci degree, that will keep your options open. From there you should be able to get work as a Sys admin, programmer or forensicator if that is where you decide you want to go. The only time you marks are going to matter is when you apply for your first job, or if you want to do a PhD. If you are sensible you will have a part time job in your chosen field before you finish your degree anyway.
