A client, Nick Winter, is a 16-year-old high school student. He came to school with a box cutter that set off a metal detector. The box cutter blade was retracted in its case within Nick's backpack, but school officials deemed it a weapon. Nick brought the box cutter to school because he volunteered to help unpack boxes of T-shirts for a football fundraiser after school. Research the issue of whether a box cutter is a "weapon" under California's "possession of a weapon on school property" statute. Be sure to cite both the statute and relevant case law.
