The question for any attorney representing you is whether there is any independent evidence of your association with the BF AND what is the evidence that proves you had knowledge that he was arrested for the narcotics violation. I hope you have not admitted knowledge of the arrest. That would make their case much easier depending WHAT you said. You should seek out a qualified attorney that is familiar with your judge and VERY familiar with federal practice. The case analysis requires identification of the evidence. If it is not in your favor then you need to be able to mitigate your position before the judge with all the above information...PS It would be good to know whats going on in your BF's case. The governments case would be hampered if he is acquitted or his case dismissed??
