If those countries have laws against making and consuming pedophile pictures and drawings (or "artwork"), I feel it's perfectly fine for people making and consuming those to be raided, even if they disagree with the law (if people could opt out of all laws they don't agree with, I'mnot sure what would be the point of making laws).

What is not ok is to watch the activities of everyone who is not a pedophile in order to catch those, otherwise when does it stop? Should they have cameras in every room of your home just in case?
