Not really. The American Bar Association actually recommends NOT taking any 'pre-law' courses, as they feel it gives students biases before they actually get into the practice of law. Criminal Justice courses are aimed towards people who plan to do things like work in corrections, prisons, or even police officers. It might help give you an idea of how the justice system works once you've graduated law school, but it will not help getting into law school or doing well at it.
Take courses that will improve your reasoning. Philosophy or any 'hard science' that requires logical steps (i.e. engineering courses) will help you do well on the LSAT reasoning section; it will also help structure your law exam answers. Writing courses will also help on the LSAT and in your exam answers.
