Sure. But objectivity has its place in court.
Objectivity is on the side of the prosecution. They consider the evidence and charge the perpetrator with the crime that evidence shows was committed. They want the right person to pay the appropriate dues for the crime committed; they have no investment in doing otherwise.
On the other hand, the defense has one goal: to spare their client from the death penalty and possibly even exonerate her.
Now, considering this, which side has the most motivation to warp case history, bend or omit facts, and present a story that has little to do with the truth?
