At least nine Detroit area high school juniors are in trouble for wearing sweat shirts bearing a design that evokes the terrorist attacks that destroyed the World Trade Center's Twin Towers.
Dearborn Public Schools spokesman David Mustonen has told The Detroit News and Detroit Free Press that the shirts the boys wore to Edsel Ford High School on Monday are "offensive" and in "poor taste." 
The boys are Arab-American, as are about half the school's 1,700 students.
They belong to the 2011 class. On the shirts, the number 11 resembles two buildings, with the school's "Thunderbird" mascot flying toward them. Printed beneath the image are the words, "You can't bring us down."
The boys are to meet with school officials but suspensions are not planned.
"The whole design gave prominence to the 9/11 tragedy, and of course was very upsetting to staff and students," the Free Press. Monday and Tuesday from the district.
The paper noted the students made the sweat shirts for $25 apiece during their winter break.
