First, this article starts with a silly comparison. Certainly we have overblown rhetoric about guns in this country and thus can’t seem to come up with any sort of reasonable regulatory regime, but that has really nothing whatsoever to do with whether or not an investigation of a terrorist incident should include investigating electronic devices. The implication that there is some government agency choosing between “going after” iPhones or guns is just gratuitous anti-government nonsense.
I think questioning whether the government is taking the best approach to getting the information it needs to investigate a crime is legitimate, but I certainly don’t think this makes Apple some sort of white knight. I am inclined to think that Apple might have been able to quietly resolve its differences with the government investigators if it wanted to, but chose to go public for brand image and marketing purposes. And judging by the comments here, looks like the marketing campaign is working.
