Or in any situation, for that matter. It is after all the 21st century.
The San Diego, California high school teachers and coaches thought it would be funny to go all out with their Cool Runnings outfits while disregarding all current mantas of society. Did the members of Serra High School being racist intentionally? I highly doubt it. They were just trying to complete their outfits. However, in this day and age, ignorance is not a defense. As authorities of kids, they should have know better.
If they wanted to look like the guys from Cool Runnings they should have lost some weight first. No way those chumbawumbas are fitting into let alone coming in under the weight limit of a bobsled.
