It’s about criminal charges, they could not use this without a warrant. Mass surveillance is something else, the government will do what the government wants to do.

The cited case was regarding a person suspected of a marijuana grow. The police used thermal imaging without a warrant to get a conviction. The Supreme Court determined it was considered a search by the fourth amendment (5-4 decision, btw). That would be similar here.

You mean that they would use parallel construction after knowing what they know after using it, and wouldn't tell you they used it. You wouldn't know they used it.

Maybe, if they were able to. For what it is I think that could be difficult though.
