Honestly, I'd rather live in a world filled with dangerous lemon drop dealers than have freedom be so limited that it makes me claustrophobic. We shouldn't have to be afraid of living our normal lives - the authorities should only spend their time and energy where it's needed. Yes, I agree that in situations such as this the law doesn't work as its supposed to. But you might feel differently if you knew a pedophile who was likely to re-commit had to live 3 km from a school.
