OK, so the Dubai assassination team made regular phone calls on GSM devices during the operation. What numbers did they call? From which ones? Well, it looks like they both used prepaid SIM cards acquired in Austria and they called Austrian telephone numbers. Obviously, that's partly explained by the fact that they probably talked among themselves, but the only reason to say that they called numbers in Austria would be that there were other numbers called, outside the group.
Strange. The Mumbai raiders' <a href="telephony used both a virtual number service in the US, and DID numbers registered in Austria and pointing at a VoIP system. This could just be an artefact of a data set of two, of course, or that somebody's Web shop is close to the top of the Google results.
PS, does anyone have recommendations for a good graphics/visualisation solution? I'm thinking of doing my own one of these. Specifically, I've not seen one yet that takes account of the time factor - there is one suspect who spent only 3 hours 40 minutes in Dubai.
