Normally you'd have independent party/institution that physically verifies and digitally signs facts.

Police officer would issue a request to that 3rd party to sign this fact.

Blockchain doesn't magically make people honest, but it can encode claims that you can verify.

But if you already have a trusted third party, then why do you need a blockchain? The whole point of a blockchain is to avoid the centralization of trusted third parties. At that point you might as well have a normal relational database / transactions with ACID gusrantees.

3rd party is just another actor in the system, they’re not running the system, they interact with it just like ordinary Joe with their private key.
