use of adjective and adverb

This sentence is long and wordy. It will be more easily understood if it is separated. I've changed some of the wording.

It seems that the end of the sentence starting with 'by better training' contradicts your first statement of striking a proper balance. If you train lawyers better to select more biased jurors, you are moving away from a proper balance.

I may be wrong, but I thought that voire dire meant the jury selection process. If this is left to the judge, then it's not eliminating jury trials, just altering the way juries are selected.

A proper balance can be struck between the justice system's desire to select impartial juries and the lawyers' interest in selecting sympathetic juries.

I would rethink the following part of the sentence.

by better training and preparing our lawyers or eliminating jury trials and leaving the voir dire to be conducted by the judge".
