Governments need to monitor some citizens for reasons of national security so surveillance is necessary, isn’t it?
There are cases where governments might surveil people but to do so they need to provide good reason and obtain time limited warrants. If governments are surveilling us illegally, without good reason and warrants, then they should be held accountable just like anyone else who breaks the law.
This need not be an all or nothing game. Just like the state needs a warrant to enter our homes, we can have laws that say that they should need one to also enter our phones, computers or any other private online accounts. Surveillance can be made a legal option once the state provides good evidence that someone is suspected of wrongdoing. And it can be made time-limited. At the moment we could be subject to mass surveillance indefinitely whether or not we have ever broken the law or been suspected of it.
