When you get out, assuming you don't re-enlist, ( most guys are re-upping), then you have a lot more options - contractor, LEO, State Troopers, or Federal Agencies.
But for now buckle down and get good grades.
As a retired LEO (but not a police LEO), I second what Austin and a few others have suggested about the military. I hear that, these days, they really can guarantee you a MOS school after basic training.
The military also has relationships with various universities whereby one may finish the completion of a degree while on duty - no matter where that duty is.
The military would be a place for you to get used to working and working under stress (something all LEOs must know how to do).
Also, I second what Venus Pax said: if you have this on your heart - and it's not just a passing dream - then you need to take steps to start getting yourself ready for it. Being a LEO is not like it's depicted on TV or in the movies. It's not exactly like being in the military either ... but the military seems to be the best "prep school" for a LEO career that I've ever seen. Think about it.
