The schools,like many employers, insist that they have the right to search your bags and lunchboxes as a condition of you being allowed onsite.Of course the school is mandatory,or schooling is mandatory,AND schools insist they acyt “in loco parentis” so ,since a child has no legal protection against parental searches,then school personnel can search too.
WE trot out the 4th Amendment but it has been eviserated by the War On Drugs and the War On Terrorism ,but really by the War On Freedom.
It's unconstitutional for a school to make you waive your 1st, 4th, or 5th amendment rights as a condition of going to the school, when the school is mandated on you by the government in the first place.
