I do believe it can be bad when circumcision goes wrong, I don't need to see pictures to believe it. It would be too triggering for me to look as I'm an abuse survivor.
Back street circumcision should definitely be illegal, surely it already is, though? If the law isn't enforced then a change of law isn't necessarily what's needed.
I would have thought it would be easier to implement a blanket ban on circumcision if the Jewish and Muslim communities were on board. Otherwise you may get more of these horrendous accounts of it going wrong, or families going to America to have it done.
I asked what powers children's services would have? Of course I could google that, but if there is a social worker on here they might just be able to tell me?
