The value of workshopping

Had to workshop a chapter of my novel on Tuesday night in class (This probably should have been posted earlier, but it has only recently come back into my mind, LOL).
Chose the chapter with the bail application (or arraignment for any Americans out there). Thought I had accurately presented both sides of the argument, both from the defense lawyer Burrows and the prosecutor/police officers, having been in many courtrooms in the past for the purposes of research (more than one of those being actual bail applications).
However, it was interesting that nearly everyone made comments afterwards to the effect of "That would NEVER happen in a court hearing"; "A police officer would NEVER say that"; "Someone would be held in contempt for making a personal value judgment", etc. Never mind the fact that I have heard the EXACT words given in the chapter coming straight out of a police officer's mouth; because obviously someone else knows better than I do (after all, they watch Law and Order and other such shows on TV, and it never happens there!)
Still not sure what to make of it. Do I take their advice because they have given it, and serve as an extra pair of eyes, and an additional perspective on the novel itself; or do I ignore their comments knowing full well that they are completely unfounded and wrong?
I hope to come to some decision soon, after all, I need to be working on the actual novel, not "fuming" over comments made nearly a week ago.
Till next time...
