The board voted 7-3 (and 2 abstentions) to completely rescind their vote in April to implement the school uniforms. It's now entirely off the table.
In addition to the Jedi costume, one student came dressed in prison stripes and dozens of other parents and students wore black armbands to protest the uniforms.
I agree with what one of the board members who had changed her mind said: this was a tremendous experience for the young people to have gone through, because they learned a LOT about how government works and how they too have a role to play in it.
So, we won. "The Force was with us" :-)
Afterwards, did you celebrate your victory at the Mos Eisley Cantina? ;-)
