I&#x27;ve thought about them again, but no.<p>IMO, mass surveillance can be effective, but only when it is utterly comprehensive. I.e., law enforcement monitors your conversations (audio and text), your location, your activities (shopping, watching videos online, etc.) and anything else they care to find out.<p>However, this basically means giving up any and all pretences to our rights of privacy and freedom of thought, information and expression. In the end, a government that implements that kind of surveillance would be way more dangerous than terrorists could ever be. And all that without making us feel safer - for who feels &quot;safe&quot; in a police state?
