Serious question.. when you do get picked up for something like that and you invoke your rights for silence. How do you get council? Do you already have a number, do you already have a relationship with a defense attorney? How do you navigate that?
The state has to appoint you one if you don't have one. And given that you have to invoke your exercise of your silence anyway, throw it in there. So something like, "I am invoking my right to silence and require an attorney." ought to do it. Having one ready can definitely be helpful. And while a DA is ideal, any lawyer should do, as they'll either be able to do enough work to get you out of there to find a good attorney, or get a real defense criminal attorney involved. If you do have a prior relationship, keep their card in your wallet and point them to that when you invoke your right to silence.
