Crime Analyst

So earlier, I said I worked as a dispatcher for an unnamed Police Department. Actually, more technically, I work as a Tactical Operations Specialist, which sounds cooler. I joined the department a year and a half ago, always with the intention of transferring to the Crime Analysis division. I have wanted this job for a long time now, and finally they have an opening. However, I am not the only one who applied.
Lets look at the facts: It is one job for about 8 applicants. My competition consists of my fellow TOS co-workers, of which two have master's degrees in criminal justice and social work. Additionally, two other applicants are police officers with at least three years of experience. However, I know I am the only Army-trained, government intel analyst that has an undergrad degree in poli sci as well as an Associate's in Intel Operations. Not to mention, numerous deployments and professional development courses in civil-military relations. I only hope this provides enough diversity to set me apart from my competition. I am nervous as hell, I know I am qualified, I am just trying to figure out the "sell" angle to my interview on Friday. How can I sell myself? How can I prove that I am more qualified than two people w/ master's degrees and two police officers? What are the best, most select words to tell the interviewers? Even still, on my resume, I mistyped a damn word. The question here, would now be do I apologize for the typo or let it slide? I have decided I will apologize for it on account of the lack of time I had to prepare my application.
Its not that I hate my TOS job, it is fun, and I love my shift. It is just that intel and analysis is more my forte and teh 8-5 hours M-F is a lot better too, but that is only a fringe benefit.
