It will easy for the police to say give me every dataset that has this GPS location or within 20 feet near it. Heck it would be even easy for a malicious Apple employee to track someone down and see where they've been. I can go here and find the Longitude and Latitude of any address. http://itouchmap.com/latlong.html
Now that I have a location I could query the database and look for any records near that location. I can now see where everybody near that location goes. The police could then build up your pattern of travel and look for anomalies or even see if you went by certain location on a particular day. But you say there are 4 or even 20 people near me that have Iphones how do they prove it is me. Most people spend their time at one of 2 locations. Work/School and Home. So I can eliminate all records that don't have those have those locations as their greatest number of entries and I have narrowed down your travel patterns. That is how they will know who you are and where you have been.
