I agree that the law isn't designed to fight evil, but many laws are designed to fight evil. It's a subtle distinction, but one worth pointing out. Surveillance is part of sense-making for law enforcement and even though I don't think that security and privacy are always at odds, and there are definitely cases where they are not zero-sum, when dealing with persons of interest in criminal investigations it tends to be the case that degrading a suspects privacy improves societies security. But it should be done right. Warrants, probable cause, etc.
