Even searching a suspect's house could never yield a full inventory of that person's friends and acquaintances, the entire record of their voice and text communications -- and all the web pages he'd ever looked at. Now, law enforcement or a government official can have all of that in two minutes and physical access to one's cell phone.
I don't believe that I have given as much thought to the subject of mobile security as I should. While I similarly employ the, "I don't have anything to hide" mantra, there is the fear (a legitimate one) that this level of information can be accessed by anyone. Scarier still, as mentioned in the article, the manner that this information is utilized by law enforcement is incredibly undefined, therefore your entire life could be logged as evidence without discretion.
