What are some of the arguments for and against the primary sentencing structures of determinate sentencing and indeterminate sentencing? Which...

I'm going to cheat and say that I want a mixture of the
two.  I think that there should be determinate sentencing, but that there should be ways
of having sentences outside the prescribed range in severe
cases.

I do not want there to be completely indeterminate
sentencing.  If you have that, you get judges giving wildly different sentences to
people based solely on their own personal opinions of those people.  That is not
just.

On the other, hand, however, there needs to be some
amount of discretion.  Crimes and criminals are not all the same and there ought to be
ways to give people lower or higher sentences in extreme cases.
