What evidence are you talking about and since when did you garner access to all of the evidence?
If you're speaking about eyewitness accounts as your evidence then
Eyewitness testimony doesn't amount to jack if you don't have facts and evidence to back it up.
A couple of examples here are Dorian Johnson saying he was shot in the back.
Also there is discrepancy in the number of shots fired.
Both examples of eyewitness accounts.
