Was the act of throwing the stones proved conclusivily to lead to the mans manslaughter ? If yes then convicition secured. If not, as would appear to be the case it cannot be proven then how can the conviction be upheld ?

Trial by jury does not guarantee a sound conviction, if it did there would not be so many miscarriages of justice would it ?

The release of these 'killers' appears to depend nothing more on a legal technicality
