Well, no, some people are ignorant, and don't care about understanding the law.
Then it is not the law! The law is a common feeling that the entire society has about 'how just' an action is. The law is not a set of rules laid down by a dictator, or a dictatorial group.
The choosers of this committee would be other members of the government who good faith is provided to to choose unbiased members.
Oh I see, so now it is moral to have a government. Aside from the obvious absurdity of this statement, let me perform the exact same set of arguments I have for every other proposition you have put forward:
If it is moral for you to elect a government, that can, in turn, elect a committee to kidnap children, then why is it immoral for me to setup my own government, say for my suburb, which elects a committee, in good faith (as I see it), which, in turn, creates a group which has the moral authority to kidnap children?
I could elect myself the government, I could be the only member of the government, and I could elect myself the only member of that committee, in good faith, then I could elect myself the only member of that 'child services agency', thus obtaining the moral authority to kidnap children.
Then I'd have the moral authority to run around and kidnap children, right?
Wrong! If its immoral for one person to do then it must be immoral for ANY person to do. How many times must I explain this to you?
If you really were unbiased, had the training so you wouldn't make horrible mistakes, and only intervened in situations that drastically needed them, then yes, you would have the moral authority. However, there would be no reason for you to exist as a separate group from the existing child protection services.
I see, and who is to determine what is 'unbiased' and what is 'the correct training'? Who is to determine what is a drastic situation?
Must I spell it out for you? Your position on this is immoral, and it can never be moral, because it is inconsistent. In fact, why don't you look up the great evils of your CPS group in the US to see the real manifestation of the immorality of which I speak?
