It's horrible to be met with such an apathetic attitude when we feel it's important, but I think you've got to do it when it feels right. We're supposed to be able to report any crime and not feel like a criminal when doing so, whether it's rape, murder or petty theft. The police are there to protect us and it's obvious the theft made you feel vulnerable.
If I felt like I was legitimately at fault, i.e. left a bicycle at the curb overnight, I wouldn't report it. But if someone conned me (gave you personal info so that you were able to feel comfortable), I would definitely report it.
I don't know about waiting for results, though. I'm not sure I'd feel confident that they would actually investigate the information you were able to provide.
