Here is another quote from the article:
"Our officers will give
direct orders or commands to passengers," explained Mike Milne, a spokesdrone for the Customs and Border Protection (CPB) agency. "It is the
obligation of the passenger to be compliant with those." (Emphasis added.) The same point was made by Tom Schreiber, CPB Staffelführer in Blaine, Washington: "This is not a situation where we're asking; this is a situation where we're
ordering you to do that." (Emphasis added.)
Blind obedience is required, thank goodness we still have a free country.
