Saying it would be an unjust prosecution should include something to back it up; the most logical outcome is that if both lawyers are just as skilled the little edge they may have by actually having a innocent defendant -or a gilty prosecuted- would help get better justice overall, I don't think I could even be persuaded otherwise until I can read about a real world nation where such system was tried and failed.
