You are saying that random strangers should be able to take kids from people's homes on their own say so. And this improves on what we have now how?
Yes because the system can adapt, fail and improve.
On the first day that its OK for random strangers to take kids on their own say so, a lot of paedophiles will be exhausted. So many kids and so little Viagra. Of course you are Ok with this as it allows the system to fail and improve.
Are you OK with it? NO? Then stop them. Or you don't want to take that responsibility ?
