At least with our homes we have some reasonable ways to know whether or not a government agent has entered it. With our technology, however, they could enter our computers, phones, tablets, etc., take whatever they want, and we would never know unless they decided to tell us. And there have been too many instances of that happening for the American people to feel comfortable giving the government even more tools to access our technology.
Perhaps if the government had behaved more responsibly with our civil liberties to date, this wouldn’t be much of an issue.
