I keep telling my wife that FB is watching her. She says "I want a bench for the porch." Two minutes later she gets ads for park benches. She thinks its coincidence.FB feeds the feds data. Sometimes even without a subpoena.
I can only imagine the stream of useless info from FB that is gathered and looked upon without hesitation. Yet how many times do we hear, after someone snaps, that the feds were looking into them years ago but did nothing about it.
