The guy who clandestinely recorded his encounter with the border Gestapo was trying to enter the United States and spend money at a mall in New York. He was interrogated as if he was a member of al-Qaeda or a drug dealer.
Of course, al-Qaeda and drug dealers do not enter the country at border Gestapo zones. Drug dealers enjoy the protection of the U.S. government and mega-banks, while al-Qaeda has entered the country thanks to the CIA and its terrorist passport program.
Only lowly citizens are terrorized at the border.
Canadian citizens are advised to avoid America (they have their own police state to deal with) and make American business suffer for the thuggish behavior of the government.
