I am not a US citizen, a supporter of the militarization of the police, or their unchecked use of power, but your third (numbered) point: "[1] Being a foreigner, I'm not protected by your constitution and the officers haven't sworn to protect and serve me." is incorrect. All persons on US soil are protected by the US constitution, whether citizens or not. Your (confusingly) similarly enumerated point earlier "[1] and your guantanamo-friendly interviews at border control" is also flawed, as there is no possible way (of which I am aware) for US Customs and Immigration to send you to Guantanamo Bay without the assent of the country you are leaving. US C&I can turn you back, or temporarily detain you, and have a great deal of latitude with respect to questioning and searches, but you are always protected by the US constitution and possibly the laws of the country you are attempting to leave depending on where you are being questioned. The reason that people were allowed to be transported to Guantanamo Bay is that they were captured as unaffiliated combatants (who are allotted few rights in the Geneva Convention,) within the borders of a country whose sovereign granted the USA custody, and allowed deportation for detention without conditions.
