No she was not on TN or anyone else's property, she was in the street. She took pictures of the adjacent residences as well. The residences are so close to the street, no one would have to leave public R.O.W. to take a picture. The only pictures taken or shown were of the street view.
IIRC, Cobra is the one that chimed in with the "break in" theory which tells me all I needed to know right there. To insinuate that a lady, who has worked tirelessly to help all of us understand the stage of this tragedy, was part of a crime is wrong IMO.
All anyone has to do to determine that the picture came from Ger's camera is view it in a Windows picture file and right click over the picture, select properties, scroll down in the window and it gives you the type and model camera used along with the date and time taken.
