The 'revenge' of prisoners on child abusers, the inevitable flood of bile and vitriol that follows has been a regular feature of the AB since Day One, and VHG, AOG and I have always sung with the same hymn sheet.
These outpourings of righteous anger are absolutely understandable, but do nothing to further the cause of justice in our society. Justice is given under a jury system, which is by no means infallible, but still the best that we have.
The notions of 'like for like' torture have no room in a civilised soceity, and indulgence of them would lead to a 'survival of the fittest' culture which would see us all doomed - including the 'I could do it ...' brigade because I seriously doubt that you possess the coldness and psychosis needed to act on your words.
Justice may be flawed, but our laws make us civilsed, and that is what we must trust.
BTW - anyone who thinks prison is 'easy' or a 'holiday camp' - think cartefully when you pop out of your house tomorrow - a freedom we take utterly for granted, and its removal is the real punishment. Think about it.
