Just because a person is found not guilty or is acquitted on appeal, does not PROVE they are innocent.
If a jury cannot be satisfied beyond all reasonable doubt they must acquit. As I said that does not prove they are innocent nor that they should not have been charged. Often witnesses, for a variety of reasons, change their evidence or the jury just do not believe them. OR maybe an error arises in the prosecution case, in which case the jury must give the accused the benefit of any doubt.
Also be aware that many writers get best-sellers based on a distortion of the facts of a case. Ludovic Kennedy was one such author.
And finally, Timothy Evans admitted killing his baby so whether of not his conviction for killdeer his wife was or was not correct he would have been hanged if he had been acquitted of his wife's murder.
