A bank's cameras cannot see into private spaces in unrelated buildings as is the explicit situation in this case where most of the people caught in the general dragnet were inside a church some distance away. And to be clearer, the data search is being done on the GPS recordings of personal property (not basestation multi-lateration records). This is the private space being searched. It's like if you carried around a journal and wrote down everywhere you went. Now the government is arguing they can draw arbitrary large general regions and read everyone's personal diary even in situations without any exigency.

This is an excellent point and I largely agree. I do wonder though: do we have a reasonable expectation of privacy when using Google mobile services?

Given how many things sorta require a phone, even basic government services, yeah I would say so. It's not just Google phones, all cell carriers are collecting location data.
