Nothing specific. I've got a crim degree as well. That and a buck eighty will get me a large coffee.
The only things to which it would specifically lend itself are, as you found, MP. Beyond that it's just another piece of paper on the wall useful for everything from infantry to pilot, but not of particular application anywhere specific.
Realistically, unless she gets into a few narrow branches of public policy, or the justice system, or continues through the academic stream, a degree in crim doesn't actually lend itself specifically to much.
