As with most things, I think that it is a trade off. There is a very delicate balance between security and privacy.<p><i>Too much surveillance</i><p>- General public feels incredibly uncomfortable due to lack of privacy<p>- An incredibly scary amount of power in the hands of whoever has access to that information ( and who knows what they will do with it )<p>- Reduced risk of terrorism and security concerns<p><i>Too little</i><p>- Increased risk of terrorism + massive security concerns due to lack of intelligence ( it&#x27;s like trying to find a needle in a huge haystack )<p>- Public feels safe due to perceived increased privacy and yet feels unsafe due to ( potentially ) increased number of terrorist incidents.<p>It&#x27;s a rather difficult problem to solve. How can we extract critical security information without invading people&#x27;s privacy?
