The comparison I am drawing is between the hollywood blacklists and the arbitrary searches of associates of a suspect. The Morrow quote seems fitting whether you think wikileakers are like persons
accused of communism or not. We are talking about two things:
1. Investigating associates of a suspect for no reason other than that they are associates, and 2. Performing searches whenever you can without warrants or any kind of direction. These appear to be fishing expeditions, quite possibly the authorities are hoping to catch an associate with evidence of some other crime that they can use to blackmail them into cooperation.
Does this appear to be wild conspiracy mutterings? Too bad the authorities aren't following any kind of process where such accusations can be aired and refuted. Perhaps there's more to it than mere association. If a warrant had been obtained for a search, we could have some confidence that the police explained the justification in a credible manner. Without a warrant, the credibility of the investigation is undermined.
The seriousness of the crime is a red herring. If it's really serious, then there ought to be even greater motivation to ensure that justice is done publicly and fairly. The argument that serious crimes justify skipping all the annoying business of rights and liberties is broken, and I call on you to clarify that you are not arguing that there are some investigations where the ends justify the means.
Finally, the fact that there have been abuses of the border search doctrine for decades is either irrelevant or even greater motivation to fix the problem. By 1969, police agression against people of colour had been a fact of life for at least a century. Was that any argument to shrug our shoulders at the assassination of Fred Hampton?
