State of Missouri vs. Darren Wilson

From what I have heard so far from the Grand Jury presentations, it is clear no decisions can be made at this point. There has not been any testimonies  that have caused me to believe that the officers/ detectives who have given statements had not done anything to compromise the crime scene. The procedures seemed to be standard and followed protocol. The only thing that stood out to me as a little odd was that the pictures were not taken by the Medical Examiner like they were supposed to be. He did mention on several occasions that it was because his camera battery was dead. It seems strange that he would not have charged his camera battery given that it is a large part of his job to take picture at the scene. Mistakes do happen, but it just comes off as weird. Besides that, the crime scene detectives seemed to not have done anything out of the ordinary and nothing from those testimonies stood out to me. I have not formed an opinion yet on the case as a whole but this is what I took from first few volumes.
