John, since you started the thread, could you possibly supply the info requested on page 2 so we know whether we're discussing something statistically significant?
I did have a look myself yesterday. I found the population size of England and Wales, the number of attempted and successful abductions (I should have looked for disappearances) and the population size of Portugal, but I couldn't find any statistics for crime. It's probably on the net, just not in English.
