I know it's a thing.

That was just my reaction reading the OP.

First paragraph: reasonable, if ignoring that access it not likely to be unrestricted willy-nilly.

Second paragraph: not as reasonable given that Amazon likely comply without issue with us intelligence, and sell the data to third parties, which the police could just buy (similar has been done) to avoid consent or legal obstacles.

Third paragraph: out of nowhere, focus on police. No mention of intelligence agency staff or say Amazon staff doing the same thing.

I just had a wee chuckle to myself was all.
