What I am proposing would certainly require a Constitutional amendment (in the US, at least). It is a departure from the "jury of your peers", which is the intention. The specificity of modern scientific evidence warrants rethinking the way we select juries. A jury of normal citizens is just not equipped, educationally, for the job. Specialists are required with intimate subject knowledge.

I am proposing that the expense of the jury be covered by the court (as it is now for citizen juries, and it is also is with public defenders), but that they not be employees of the court. Again, like public defenders.

It certainly wouldn't be a perfect system, but I believe it plugs some of the holes that have appeared in our current system of jury selection.
