Lots of thoughts on this but, in a nutshell...
1) "Stringing them up" - there is no place for capital punishment in a civilised society. As abhorrant as these individuals are, society has to set the moral benchmark above the actions of the most wicked: we don't stoop to their level. Unfortunately, as many of us are parents / grandparents / uncles / etc to children we all love, we are very subjective when it comes to paedophiles. The Law is there to ensure justice is objective and fair for all. That being said, paedophiles are recidivists so more should be done to ensure those who are convicted have zero contact (or as close to that as possible) with vunerable children ... either that or chemical castration.
BTW - I'm saying this as someone who found out that my grandfather - who was alive at the time - sexually abused my mum and her sisters when they were young. When I found out I had to be forcibly restrained from jumping in the car, blasting over to Southway and pummelling the sh*t out of him. I wanted him dead ... but that was my emotions taking over. My mum (who was the victim, after all) didn't.
2) A tad unfair for a few comments aimed at FIFA. They may well be corrupt ar$eholes but I'm sure the powers-that-be there wouldn't want to brush accusations under the proverbial carpet. Taking a back-hander and a couple of rolex watches is one thing, but abuse is entirely different. At least wait until we see how they react before condemning them.
3) I read a few interesting comments from the Scottish FA regarding this a few days ago - especially as rumours were rife some time ago about the sexual abuse of youth players at Celtic in the 60s and 70s.
4) I can guarantee you this won't be limited to football. There will be paedophiles trying their luck in other sports where they could have access to children: tennis, athletics/gymnastics and swimming most definitely spring to mind.
