A failure to read Miranda rights almost never results in a case being dismissed. First, the cops aren't always required to read them. Only if you are (1) in custody and (2) being asked questions that may lead to incriminating responses. If one or neither of those factors apply, the rights need not be read. Again, if there was a Miranda violation, that doesn't make the case go away. At best, it will get the statements you made suppressed. You really need to have a lawyer. You should consider asking the judge for another financial evaluation to try to get you qualified for the public defender. If that doesn't work, try shopping around in your area for an attorney that you can afford.
