Sorry -- I missed the point of your question. I don't think individuals can just buy the data the same way a bounty hunter can simply buy cell tower tracker information on an individual basis.
I'm not very informed here, but I suspect those purchase arrangements are made by very large companies, and that by the time small companies or individuals are purchasing data it's been resold and transformed.
