Nothing to hide, nothing to fear is a pretty well understood fallacy (http://www.computerweekly.com/blogs/the-data-trust-blog/2009...) (which im kinda sad to see on HN).

As for patterns and keywords, your "guarantee" is pretty shallow and baseless. A reasonable time i guess to quote Niemöller: First they came for the communists, and I didn't speak out because I wasn't a communist.

Then they came for the trade unionists, and I didn't speak out because I wasn't a trade unionist.

Then they came for the Jews, and I didn't speak out because I wasn't a Jew.

Then they came for me and there was no one left to speak out for me.
