True, but keep in mind jurors are drafted and their oaths are dictated to them by the court. Personally I would be more concerned with justice as I see it and less concerned with venerating the state.
Others have taken that position as well. The problem is that if you know up front that you will find for one side or the other, and the lawyers do a half way decent job on voir dire, you are going to have to lie under oath at some point. If that doesn't give you pause, and you don't brag about it, then you will probably get away with it.
The OJ case was pretty much a case of jury nullification, and nothing adverse happened to those jurors, for example.
