There was a recent poll in which the above question was asked and a large number of Americans answered "fairness".
This scares me. A lot. Especially since the vast majority of those who favored "fairness" identified themselves as belonging to the political party that'll likely control both Congress and the White House come January.
I truly don't understand this viewpoint.
"Fair" is a highly subjective thing, while the Constitution is far more stable. Yes, judges do occasionally allow their personal biases to override the law, but it's very rare -- far more frequent is the situation where the judge decides based on the law, even though his personal opinion differs. This consistency and stability is fundamental to a free society, yet all these people are willing to throw it away.
