<p dir="ltr">Dennis,</p>
<p dir="ltr">It goes without saying! If NIS can intercept the communication between terrorists then they can be stopped before they do any harm. </p>
<p dir="ltr">Actually, one use case of Big Data is national security. All the communication within a country is filtered through 'The Machine' and one becomes a 'person of interest' if his/her communication makes them one. Otherwise the intercepted data is discarded. From here, human assets can dig deeper and prove a suspect's innocence or otherwise. <br>

<p dir="ltr">Ben,</p>
<p dir="ltr">LOL! Encrypted communication apps you say? If the Government wants access they will get it! Just read what happened to Blackberry's encrypted communication in India!
