What would your internet searches reveal about you if others could scrutinize and second-guess them? It's something to think about, given that the big search engines, like Google, store search histories and make them available to the authorities. In fact, as happened in a recently decided Colorado case, police can start from search terms of interest and pressure tech companies to surrender the identities of anyone who has surfed for specified keywords. The decision is chilling for anybody who has ever pondered their online history in the hands of a stranger—or who just cares about privacy.
