Legal Question in Criminal Law in Maryland

The police must have either probable cause or consent to search. The judge would decide whether they did. An experienced criminal defense attorney can help you evaluate the prosecution's case, any defenses that you might have, and any plea offer that might be made, so that you can decide whether to go to trial. Consider seeking a confidential consultation.

There must be probable cause for the initial stop, and the cop gets to make an incidental search around you for his own safety. It can vary with the circumstances, which you don't fully describe in your question. If you have been charged, you should engage counsel or qualify for the public defender and then fully investigate the facts and circumstances of your defense.
