If the pap told the world where she was, it would bring in competition. The pap would no longer have the exclusive pics and video to sell. I believe there is more. We saw TMZ buy one portion of the video, and Huffington Post purchase an additional portion. Perhaps the pap did offer a location for a higher price, but none were willing to pay.
I think that the nature of this particular professional quality video as surreptitious suggests some caution. This is being released very carefully. The video is edited to omit time she spends away from the window in the store, or perhaps to omit location material in the street walk segments, each cut is just a few seconds.
The first is 13 seconds. It is cut between her walk down Lennox TC and her opening the door to Old Navy.
Then we get a 4 second segment before another cut. That's most likely because she walks out of view from the close of the door into the store.
Then we get the 16 second segment of her looking at scarves and bags. Cut.
Then we get a 13 second segment of her looking at the red dress. Cut.
Another cut to her back at the scarf rack for 11 seconds. Cut.
Last cut at Old Navy has her exiting and walking passed couple with child, and is 15 seconds. Cut.
That's six cuts for 1 minute and 12 seconds of the tape. I am not going to count the rest of the cuts in the various 54 seconds of street walking. I just wanted to make a point.
This is a cautious release IMO. Cautious to not let anyone else scoop this, and cautious as in there is more to release. IMO.
