My high school taught me that i didn't have civil rights guaranteed by the Bill of Rights in their building. I have literal classrooms full of witnesses because I enjoyed my 1st Amendment right very much. A teacher was fired from the district years later for teaching kids about their right to not answer questions when the school gave every kid a questionnaire regarding their parents' possible cannabis use.
Our nation is where it is because this is happening across the whole country and nobody is suing these schools for lying about when we have rights and what those protections mean, not to mention blatantly violating the rights of individuals while being at least partially funded by tax dollars.
PARENTS: Please sue your kid's schools if they do garbage like this. Not for your wallet, not for your kid's college fund, but because policing, schooling, court are businesses that care about how much money they have. It is temporarily tough for taxpayers when people sue govt or schools, but not doing so has created entire generations of police who literally think they can get away with murder when people exercise their rights, judges and DAs who allow it, and communities who victim shame those murdered and tortured by police for simply refusing to talk without a lawyer present. These number of murdered individuals who are not armed are in the 1000s every decade.
PS: if you back a political party, D or R, your party is causing this problem, not helping it- it was pretty easy to tell, even for a teen in the 1990s that teachers in both lanes were committing to these lies
