Conclusion to Darren Wilson Case

I have found that even after hearing 23 of the 24 volumes I am still having a hard time deciding whether or not Darren Wilson should have faced charges. After re-looking over my notes it seems to be that there are roughly two stories about what happened between Wilson and Brown. The first story can be boiled down to the idea that Brown was holding Darren Wilson inside the car while repeatedly punching him. Then after Brown stops running away, he turns without his hands up and charges back toward officer Brown in a manner that seems like he is a threat to Wilson. Some of the other small aspects to this story that change between every witness are whether or not Brown was reaching for a weapon. Among the witnesses that all seem to give testimonies similar to the story I just gave, most of these people believe that Wilson told Brown to stop and put his hands up repeatedly.
The other story that I seem to hear the most is that Brown was only putting his hands into the police car in an attempt to get away from Darren Wilson was holding him near the car. Then jumping forward to when Brown stops running, he turns around with his hands up and slowly walked toward Officer Darren Wilson. With Witness testimonies most similar to this, many of them believe that Wilson somehow started the altercation and never gave Brown verbal warning to stop. I am struggling to choose which story to believe. If Brown did in fact charge Wilson, never had his hands up, and repeatedly punched the police officer than I think that Wilson was in the right to shoot Mike Brown. But if in fact the other story is true than I do not think that Wilson had any justification to shoot Brown and should have faced charges.
If at this very moment in time I had to choose a story to side with I think I would side with the second story. I would side with the second story for two major reasons. The first being that I felt there were more inconsistencies and unreliable witnesses in the first story. The second is that after reading the Physicians Assistants testimony from my volume and learning that Wilson did not have any noticeable bruising to his face, I don't think that Brown could have been punching him that hard. This leads me to believe instead that the read marks on Wilson's face where from Brown pushing him to try to get away.
