They protect people by one because of the amendment’s they give us freedom of speech religion, press equality and unfair treatment based upon race etc…. But to be truthful the answer to the second question I would say no because even til this day America can’t be called the land of the free because we aren’t free yeah the laws say that ppl shouldn’t do this or take that right away from someone but they do we aren’t equal people still get judged and discriminated against they get attack and targeted.
