"Making" Does Not Mean Making
"Making", as in "making indecent images of children", does not mean making. Not in the way you're probably thinking, anyway.
"Making indecent images of children" includes making copies of existing images of children, including temporary, transient images, such as on a computer screen when browsing the web. Possession includes being in possession of the temporary, transient image that briefly exists on your screen. I'm not talking about image files here (though they also count), but about the literal, physical, visible-with-your-eye images that exist right in front of you on your computer screen.
If someone sends you an image file, or a link to such an image file on the web, which you know to be an indecent image of a child, and you then choose to display that image on your screen, you are literally "making" an indecent image of a child, since you are literally causing the visible, visual image to exist on that screen.
Of course, "making" also includes pointing a camera at a child and taking a photo.
As for what I think was "Easy" AC's main point, about foregoing some opportunities to catch the baddies in order not to deprive the majority of their basic rights, I must ask you to consider the policy of having CCTV in everyone's homes, in all the rooms, to make sure that abusers have no opportunity to hide their abuse behind domestic privacy. Would you support such a policy? Or would it be too extensive an interference in everyone's basic rights to be justified?
Harm to society - which of course includes children - is not minimised when the measures intended to reduce harm actually do more harm to society (in other ways) than the prevented harm would have done. It's not that a little bit of child abuse is a price worth paying for our rights and freedoms, but that the price of preventing all such abuse can end up harming society more than the abuse itself, and isn't a price worth paying. (The law of diminishing returns applies here.)
Would you let ten children avoidably die by diverting resources away from them to save just three other children from abuse?
Having said all that, I don't agree with "Easy" AC on everything. Abusive photos of children do actually form part of the abuse.
