In the U.S., prior to your trial, prosecutors are required to disclose all evidence that they may bring against you in court, as well as all evidence that might support a verdict of Not Guilty. Failure to do either is a serious breach of law and ethics, and would inevitably result in a reversal of any conviction. After an arrest, however, prosecutors are only required to state the nature of the charge against you -- the evidence for or against you is only required to be given in a "timely" manner prior to your trial.
