Which is why it is reasonable to be more suspicious of white loner types in schools if they have anything suspicious on them. Just as if we are being realistic a muslim kid with a suspicious briefcase with wires and no clock face in it would would be treated with suspicion.
This notion that some sort of contextual profiling based on race or religion or any other subset is wrong, despite it being based in the reality of life, is puzzling to me.
The point that the kid probably wouldn't have been treated with the same level of suspicion if he was white is true, but that is based on the real world fact that the majority of people blowing themselves and others up in 2015 are muslims, often young males.
No one seems to kick up a fuss when a white kid with a slipknot tshirt is profiles at school, yet profiling other groups or simply having healthy diligence to potential threats from other groups is deemed as racist. If this kid had simply explained to his english teacher what it was, this would of been settled without the whole fiasco.
