Professional Jurors?

In today's courtrooms, issues are brought up that many jurors admit they don't understand. Forensics, especially, has become very sophisticated and complex. Lack of knowledge and understanding on the juror's part could potentially be the difference in life or death for a person. Jurors are just folks like you and me, and I know I might be intimidated by a trial and all the details if I was asked to serve. Do you think there should be professional jurors as opposed to lay people? Professionals could be trained in all aspects of forensics, the science of DNA, psychology, human behavior, etc.
