Was going to say that too bufobufo. He has clearly overstepped many lines in the sand, and I agree, probably does see himself as some sort of crusading uber doctor cum Cracker type, but he did unveil serious attacks by parents on their children, and saved those childrens lives. Filming was not all covert, some families were told clearly that their baby would be filmed to watch for episodes of stopping breathing, and they parents still suffocated them.
And if you work in an area where you do see unthinkable things like that, not once, but time and time again, in different families, maybe that distorts your view of normality.
This is not an excuse for the accusations he has made, or for the secret files, but just a small counterbalance - he did make a significant contribution to child protection, and I think this is probably what the Royal College of Paediatricians is referring to.
