Where does the ruling discuss public places? The article quotes the ruling as saying, “An individual has a reasonable expectation of privacy in records about his cell phone’s location.” I don’t think a ruling about private records held by a private entity like google or a phone company naturally extends to surveillance of public places.

I don't think it's reasonable to have privacy in a public place. All other arguments follow from there.

What do you think should be "private" when you step outside your home?
