The slippery slope argument can be overused. But any surveillance capability results in “good” as well as bad actors, frustrated with the current limits, asking for just a little more formal power or finding ways to justify informal drift in practice. The only way to stop surveillance creep is openness and clear principles more coherent than a recursive “well they have been responsible so far, so far as we know” argument.
