It really does not matter. In a free democracy there should be no surveillance of innocents. The sole feeling of being watched alone changes people (someone help me with the citation here).
> In a free democracy there should be no surveillance of innocents
I agree with the sentiment, although I might rephrase it as "There should be no surveillance without a warrant," since in some cases you can't know who is innocent or not without doing surveillance. A warrant is a good implementation of due process for people you want to investigate, but who are still (in theory) presumed innocent.

There is also something named after Caesar where if you treat people like criminals they will become criminals (someone help me with the citation here).
