“Despite the fact that violence has always been present, the world does not have to accept it as an inevitable part of the human condition,” says the WHO guidance on violence prevention.
But this is bullshit. Humans are a violent species. Always have been, always will be. The only question that's relevant is: when is it acceptable that violence be used? Ideally it would be a bare minimum, and by people who have nothing to benefit from it. If there's a crack house with a kid that needs rescuing, or a bank robbery gone bad with a hostage, I want somebody somewhere to be using violence.
Public health approaches to social problems are interesting, both because they have some statistically significant benefit -- and because they tend to over-generalize what the problems are and leave out many important edge cases. You can't say they're bad because there is progress to be shown. But you always wonder how many edge cases were overlooked and if overall we aren't institutionalizing a hardcore subset that will never be solved at the expense of making the problem simple enough to mentally engage with.
