The article totally contradicts you:

Among computer forensics specialists, those location logs--which record nearby cell tower coordinates and time stamps and cannot easily be disabled by someone who wants to use location services

And worse still, the article clearly shows this data is already being used by law enforcement for unmonitored tracking.

That doesn't contradict him at all. "cannot easily be disabled by someone who wants to use location services" is totally in line with "when you launch a location-aware app".

Also, I didn't see the part of the article where law enforcement is using this for unmonitored tracking. They can pull the data off your phone once when they arrest you. But how do they continue to keep pulling the data off your phone? If the police take my phone from me every day, I don't think that qualifies as unmonitored.
