Why is clandestine surveillance of everyone bad? Because anyone with more power than you and the will to abuse it can simply label you as an 'undesirable'. If I'm a local police officer with access to surveillance data, and I see something about you that I don't like, I am much likelier to act against you or your family or friends. And since I spied on you invisibly, you'll never know what list of 'undesirables' your name may be on, or why, nor can you ever get off the list. As an undesirable, I (as a bureaucrat hungry for power) might uninvite you and yours from my college, business, bank loan, job offer, or I might simply charge you more for goods or services. Given the power, I can make your life hell for reasons you'll never know and have no redress to challenge. In 1870s to 1960s America these kinds of off-the-book practices were called 'Jim Crow', intended to repress minorities and especially blacks from the civil rights and protections that were theirs by law. If our 21st century government regresses to the same state the FBI did under Hoover -- not inconceivable under Trump, since it already has occurred under Obama as he allowed CIA and NSA to escape oversight from congress or the press and hide from their abuses of constitutional law -- the likelihood of history repeating itself using domestic espionage has become almost a certainty. If you still have doubts about the threat to everyone from unlimited domestic surveillance to big and small, innocent and guilty, then reread Orwell's 1984. And never forget that EVERYONE is part of some minority that will become unpopular eventually.
