Fort Dodge,IA teen tried for seperate murder and stabbing

This case is from my hometown and is suprising to me because I personally know this kid and my brother was good friends with him. Bryce Gully was being charged with first degree murder and robbery after supossibly shooting a man during a drug deal and bragged about it and sent pic messages with a gun and money. There are cameras in place in "crack ave."  in pleasent valley (down the street from where i live) that the police were using for surveillance on the drugs. It went to court and he was going to be charged as an adult at 15, but was found not guilty. T he reason for this was a combination of things. They had a bunch of  kids from the neighborhood come in and say so an so  did it and there was no clear descritption between all of them but there was a concensus from the people who were in the car with matt huffman when he was shot. This kid had a long string of criminal charges prior and they found him hiding under a bed. The second reason he was not convicted was because they had a minor error in the evidence and gully kept pushing for a trial since you can never be tried for the same crime twice. He bragged about being unstoppable afterwards until  he was later charged with an unrelated crime a felony for stabbing another kid. Hmmm.. I'm pretty sure he has a patern going on here    here are some of the links you can find info. on http://www.whotv.com/news/who-story-gully-trial-051209,0,4798942.story http://www.woi-tv.com/Global/story.asp?S=11920122 or just google his name . So why do some guilty people go free is it because of other variables such as age etc.. The victims family even forgave him and the jury said they didn't want to possibly put an innocent kid behind bars?
