All i see is an increasing descent into barbarism, cause by people's panic of everything. It will only get worse.
A young lad ( for me a child ) was shot to death by an armed vigilante who was following him and got a deserved beating.
Such vigilante not beinh man enough resorted to a gun he was allowed to carry on himself and cowardly shot the kid.
As some guy said, it may be that the prosecution failed its job, or in any case that the system worked, but not justice in my opinion.
If it was my boy, this vigilante would be a goner, speaking of barbarism.
