Of course, it’s obvious to a sane person that blanket searches such as NSA “whole pipe” data capture are seizing electronic records and communications (email and phone records being analagous to physical letters and phone bill detail and them some; note the term email refers to electronic mail) from literally millions of American citizens.
And without a doubt almost none of them have absolutely anything to do with terrorism, and if there was normal police investigative “legwork” done for each of these people, this would be obvious rather quickly.
Which is why law enforcement investigations never use the “brute force” method of finding suspects, where every single citizen is considered a suspect and house to house searches conducted for entire towns. Not only would it be unconstitutional, it would be very ineffective, as compared to narrowing down the searching as much and as soon as possible.
Of course, if this were actually to be done regarding terrorism, the first criteria would be islam, and then finding the terrorists would be a realistic proposition.
Since this terrorism is merely a tool of the financial oligarchy, if the path were followed to its end, this it would lead back to them. But we never even start on the correct path, islam, so the financial oligarchs are safely hidden behind it. And they get to have the Executive Branch leadership continue to use the full force of the government to root out and marginalize any and all significant threats to their new world order goals.
While police without a warrant may not have to let the driver leave without being searched, that wouldn't imply that they have the right to search without a warrant. I would posit that a driver should be within his rights to wait with his car until such time as police can produce a warrant, and that police who are preventing a driver from leaving should be required to make a good faith effort to get the warrant as expeditiously as practical. In cases where a warrant would clearly be justified, a driver could save everyone's time by simply consenting to a search. On the other hand, if a warrant wouldn't be justified, a driver should be entitled to refuse.
Note that even if it's likely that a court would rubber-stamp a warrant, requiring that the cop apply for one would require the cop to document what he believes to be legitimate basis for the search before it is conducted, and prevent a cop from conducting a search and then using his findings to formulate a plausible justification.
