&gt; If privacy is a human right that cannot be violated ever, how are going to deal with criminals that use services such as WhatsApp?<p>By finding evidence that does not rely on services such as WhatsApp. How did anybody ever get convicted before the age of WhatsApp, or for that matter the invention of the telephone. It&#x27;s not as if wiretaps and cell phone messages are the only kind of incriminating evidence that can be found on the vast majority of crimes. And if that is the evidence that stands between a free man&#x2F;woman and their conviction then maybe it is better that they go free because it is all too easy to forge such evidence or to plant it.
