Some students at New Prague High School are in more trouble.  A camera captured several young fans flashing what appears to be a white power symbol on Wednesday at the Minnesota high school hockey tournament in St. Paul.  The school district says the student showing the OK sign had no idea the signal could be interpreted as racist.  In another incident, Robbinsdale and St. Louis Park school districts announced they would not play New Prague in sports after their player received racist taunts.
