Because there are so many cases that come through the courts, I think only cases that are very questionable or the defendant has committed a truly heinous crime should be up for Judicial Review.
I think there should be a balance between the both of them. Because of how much has changed over time, things cannot be held to the same standards that they used to be. However, I think that if they were to base it too much on current changes, the Constitution would progressively stop being so highly regarded by U.S. citizens.
