I also think that is profoundly unjust, and unfortunately it is not simply a question of being a US citizen or not: US citizens who are arab or muslim are more likely to be suspected of acts that could be considered to lie within the vague legal category of Terrorism. So it seems that non-muslim and non-arab people (whether US citizens or european citizens or otherwise) are less likely to be subjected to exceptional treatment, to be detained without trial or be killed in extra-judicial assasinations etc. It seems the divide is more on a racial/ethnic line than a US-citizenship line.
