So, no serious suggestions then other than the stocks and meeting the victims.
What I can't understand is, what motivates someone to vandalise a children's cemetery? What sort of values have been instilled (or not) in order for someone to commit such an outrageous act? One thing we have to face is that these sorts of problems including the teenie mothers is very much a British problem. I'm not saying they never occur in Europe, but not on anything like the same scale.
I think short term Draconian measures are called for NOW. This means curfews and some sort of corporal punishment. Not flogging or violent means, but something humiliating like the stocks.
