Miranda v. arizona if we are all charged with knowing the law, how could the court find that miranda needed to be informed of his rights by the state? could miranda be tried again for the same crime? what justification would the court have in imposing such a burden on the police? would they not be practicing law by giving such legal advice? was excluding the evidence (the confession) the only sanction available to the u.s. supreme court? can you think of some other sanctions that would still allow such evidence to be used but protect the innocent person who might be subjected to such treatment.
