Again I don't think its trying to wave it off.
Its trying to be reasonable about what can actually be achieved and checking traumatised childrens naked (many of whom would have been removed for sexual abuse) is likely to cause much more damage to the vulnerable than it prevents. If it is deemed as protective then it should be for all children presumably? Would you allow it for your toddler if they were living with a step dad?
It's really easy to assume there was some massive thing that was missed, its because they are gay and skipped the queue/checks, theres a loophole that can be closed and we would all love that to be the case because all the blame can be pointed and it would be easy to prevent. Actual child protection is much greyer than that, and isnt fool proof in the slightest, its all judgement and what can be proved.
its a lot of stuff from non adopters with no experience of the system or current safeguards who won't be affected or whos kids won't be affected by what they propose.
For example the a+e visits are obvious in hindsight, but it was only three visits, if I remember only one of them was because of an injury, the rest had diagnosed ill health. As a social worker you aren't going to be questioning a diagnosis and a kid that's been given antibiotics.
I know its fairly common for adopters pre adoption order to go to a+e more regularly because you have to document bruises and any injuries, have less parental discretion, and youre a new parent with all the fears that come with that (but with a moving toddler and not a newborn!). We were questioned after our visits, and i actually know many people who were very scared to go to a+e when they should have gone in the post placement pre order bit. I wouldnt want that fear increased because i think it would hurt more children than it saves if its any more draconian than the current way of have face to face follow ups anyway.
Its the same as not wanting to see the foster parents, a red flag in hindsight but completely ordinary in adoption circles.
The same with checking phones, theres been nothing in the changes that suggests pre adoption there was anything to find, so it wouldn't have helped. Even if there was Social workers aren't police, they don't have the software, legal standing etc to get what the police can pull off.
The whole thing is about using the resources they have to prevent the most harm. Without a sudden army of social workers, prospective adopters, medics etc then the limited time needs to be used wisely, and anything that's so time intensive needs to have a reasonable chance of being preventative.
Again the system needs a certain level of flow. The resource needs to be shared between different at risk points in the system between managing social worker time, support and being able to physically remove kids.
It's a weigh up of risk of too few adoptions means that more kids are left in foster care, and more kids are left in risky homes because theres no foster care space, or teens are booted out early into risk situations to make room. All things that have proven negative outcomes too. There isnt a no risk solution
