Similar policies were endured by Americans during World War II, with no lasting ill effect. And we didn't have hundreds of thousands of enemy (outside of POW camps) inside the country then. NOW we do.
Interestingly, the same policies were undertaken, publicly and secretly, during the "golden age" of the klintons, with the approval of this fascist nutcase. Anybody remember the Clipper Chip and Carnivore? The IRS and FBI investigations of political opponents? When these programs finally made it into public discussion, kneepadders like Glen T. Martin cheered, swallowing the explanation that it was needed to protect us from "gun runners, militia, tax cheats, and pornographers". As long as liberal turds like this still cheer the memory of Waco and the lesbo-fascist attorney general of that era, they have no right to complain now.
