Should we have blue ribbon juries and judges for trying cases that relate to really tough issues such as scientific or genetic questions, or issues like GMOs, or does that violate the trial by your peers idea?

For tough issues that involve concepts that may be beyond the average joe on the street, like genetics, GMOs, environmental things, pollution, etc, should we have special juries screened for their understanding of these issues or should we use anyone off the street, regardless of their ability to understand the issues? Is this an example of elitist thinking? Or reality.
