when i went through it many years ago in LA, they were already treating non-whites like third class people, so this doesn't surprise me (though in the defense of the mpls office -- they were the exception; they were courteous to everyone and didn't make people feel like criminals). fuckwits. makes me want to move canada far away from them. i am so not looking forward to crossing the border later this month -- though, hey, i am white; they tend to not even check my papers. i can't tell you how much in awe i am of their amazing terror prevention measures; your head would explode, since you don't do sarcasm.
never been fond of US immigration
