When i got burgled I remember telling the police I was unlucky to miss them as they only had a 5 minute window, the lady doing the fingerprint checking then proceeded to tell me I was lucky as I likely would be in hospital if I interrupted them. Not sure I agree with her though, don't want to make it easy for burglars.
Sadly I expect like my case, if they get no lead's within a few days the case will get closed, the police are swamped.
Problem is you just never know.
