Racism by Fiat? In these United States?

Two states:  Washington ; Michigan..
Two identical laws: "Zero Tolerance for any weapons on school property"

Pocket knife

Two Cases: 
- Black female student in Michigan forgot a small folding pocket knife (that her grandfather gave her) was in her purse at a high school football game. It was discovered and she was expelled.... Zero Tolerance!

Kirpan

- Sikh male student in Washington State is allowed to wear an unfoldable dagger under his clothes every day to his elementary school. School District superintendent says that the Kirpan Dagger is 'fine with school officials as long as it is hidden?'

Say what....   Recently we've read about events where a five year old was expelled for biting a cookie into the rough shape of a gun..... an eight year old girl was expelled for point a crayola at another student and saying "Pew Pew"

Zero Tolerance, right?

Now, tell me again about the Sikh youth going to school every day with a Kirpan dagger under his shirt in a Zero Tolerance state.....   I think I missed the point!
