By actually investigating thefts. Me and my friends had several bikes stolen in a Belgian train station's bike park and police do not check cameras, even if you can timebox the theft within 3 hours. "No resources to investigate".
You're right, I'd rather have them hiring dedicated detectives on this to enforce existing laws than making new laws and state infrastructure. Of course this is a political discussion.
Non violent theft and most violent thefts aren't even investigated, that's probably what they meant. They're illegal and punished but the sheer amount of them mean the law is ignored in most cases
