I will never understand how a murderer can ever go free.
As noted above, the jury did not find him guilty of murder. As I stated earlier, the jury was appalled at the severity of the sentence that the judge gave him.
I find that juries almost always do quite well. Obviously, this is not absolute, especially in cases where the Judge withholds important information from the Jury. But, from everything I have read about this case, the Jury made an informed decision.
Yup and that means the men are less dead.
