How would you like if the government told thousands of people that you’re a pedophile?
Not much? Well, the “war” against child abuse just caused a little bit of collateral damage: Visitors of 84’000 domains got a warning that they tried to visit a site which is “… affiliated with creating, distributing, and/or storing child pornography.”
Oops. Imagine you spent years to create a reputation and it’s destroyed like that. That’s the reason why the law starts with the presumption of innocence. If you start from the viewpoint of “guilty,” too many innocent bystanders get harmed.
Which is what’s wrong with the current situation, no matter if it’s child abuse or war. The thought “no one is truly innocent” directly leads to the conclusion: “It doesn’t matter how many people we hurt, as long as at least one of them is guilty of something.” It’s an excuse for excessive abuse of power.
Justice means to find a balance between the abstract, idealistic demands of a law on paper and the actual, real-life situations. Bypassing justice is always unjust.
