Well, they only have a copy of the passport. I'm not sure how useful that is as a travel document. Other people have pointed out that it has enough information on it for identity theft to be a worry, though. In which case invalidating it is probably still the right thing to do.

I wouldn't take the police's word on whether on not you need a new passport. Contact your country's passport-issuing organization and ask them.

I think you're misunderstanding, or maybe misapplying Kerchoffs's Principle. "A cryptosystem should be secure even if everything about the system, except the key, is public knowledge." just means that you shouldn't be relying on the secrecy of the algorithm for security. Keeping the algorithm a secret may (or may not) increase security, but it can't be required for a particular level of security. NSA designs their algorithms under the assumption that opponents know how they work. They don't publish them so as to not make it any easier on the bad guys than they have to.
