In yet another in a long string of rulings watering down Miranda and other search and seizure related rights, the conservative majority of SCOTUS has ruled that you have to speak up if you want to stay quiet.
SCOTUS had already ruled that you have to specifically request an attorney in order to invoke Sixth Amendment rights. If you invoke your Sixth Amendment rights, they can’t just leave you and come back to harass you later. Therefor, if you are arrested from here on out, to cover all bases, you should say something along these lines:
I hereby invoke my Fifth and Sixth Amendment Rights to silence and legal counsel. I will not speak to you until I have consulted an attorney.
After that, you only have to answer booking questions. But make sure you are clear.
