What is an acceptable murder rate for society? I think quite obviously, no one actually wants murders to occur. We all want there to be zero murders, but that's not realistic. In a modern society, murder will happen, so we have to decide what are the trade-offs societally. We can make and enforce laws, then make and enforce more, and so on. Ultimately, a society with a 0% murder rate isn't utopia; it's a police state where no one is free. On the balance, I think that society is worse off than one with an otherwise "acceptable" murder rate. This is the calculus of those arguing against CSAM scanning. We all agree that we don't want CSAM, but is the cure worse than the disease?
