Ian, please don't deliberately misread my post, OK?

So what you’re saying is that fuck the dead child he had it coming...and fuck the one that killed him he didn’t know what he was doing.
Did I say fuck the child who's dead? Did I say fuck the one that killed him? Now, did I? Huh? Nope, I didn't. I said that nobody is to blame. I guess the guilt lays with the 10 year old and his parents. But that's just moral guilt, not legal guilt.

OK, that being clarified, let's get to the next point where you got me wrong:

So what you are also saying is that when your child is 4 years old you will let her/him play in the [recreation ground/play area] unsupervised while you go shopping for nice clothes.
Did I say unsupervised? Did I say that I'll leave her in the playground while I go shopping for nice clothes? Did I? Nope, I did not say that. All I said was that it is impossible to supervise a 4 year old 24/7 without locking them up.
Nor is it beneficial for the child. That's my opinion. Yours might be different, but don't imply that I leave my child and go shopping nice fucking clothes, willya, puleeeze?

Next:
Are you for real? I suppose there is no such thing as child murderers or paedophiles in your country, how very lucky you are?
Yes, there are child murderers here too, unfortunately. Pedophiles, too. A very few very unfortunate children get killed by strangers here every year. A lot more are abused.
But, you know what? The vast majority of children who get killed and abused get killed and/or abused by the persons who are supposed to supervise them. I'm pretty sure that's no different in good ole England.

In the UK all children of 4 year old have a person looking after them at that age, but then we might just be mollycoddling them. I just wonder how many more mothers think like you....well we know of one because her child by the report has been strangled.
I live in a neighborhood with 48 houses. In each house lives a family with children, age 1 month to 20 years. That's roughly 120 kids and counting. In the middle of those houses is a playground and there are always children of all ages playing there. Sometimes a mother or a father is with them, sometimes there isn't. With the real small ones there's always an adult there, of course, but if they're 4 years and upwards, it apparently is believed by all of those 96 parents that they can fend for themselves for some time.
So far, no child has been murdered, no child has been abducted, no child has been molested or abused. One 4 year old boy has been hit by a car emerging from a parking lot (without suffering heavy injuries, luckily), though, while cycling on the sidewalk. That would have happened too, if his mother had been watching him every single second.

So, yeah, maybe Swiss parents are more relaxed than British or American. Looking at crime stats, I guess we're not doing it all wrong, though.
