I think it&#x27;s important that we recognise the distinction between targeted surveillance and mass surveillance. Within a legal framework that recognises the right to privacy as the default, surveillance is a necessary law enforcement tool. This kind of device is aimed at that kind of surveillance.<p>I think a lot of people tar all means of investigating crime with the same &quot;surveillance bad&quot; feather, and they&#x27;re espousing a pretty extreme anarchist viewpoint that they don&#x27;t really hold.
