How Do You Select a Federal Lawyer?

There truly is no shortage of lawyers in Oklahoma. However, just like you would not consider a dentist for spine surgery, you may need to be more rigid and selective when it comes to picking a lawyer to defend all you have built and all that is important to you: your business, your family, your freedom.

Federal litigation and federal criminal defense work is not for everyone. It’s not a hobby to negotiate complex investigations with top-notch trained FBI agents. If your lawyer misses the routine, the experience, the confidence, your federal case could go to prosecution for no good reason.

Oklahoma Federal Criminal DefenseAt least initially, most clients take a simplistic approach. Because they consider themselves innocent and because they have done nothing wrong (or what they have done wrong they did without criminal intent), they think the government will back off. Many people truly think things will resolve by waiting. Out of the many mistakes “subjects” of federal government investigations can make, hesitation is probably the most common and the most fatal one. Don’t wait. Don’t let the government roll you over because you hesitate or because your lawyer lacks the knowledge as to when to intervene and when to go into the offense in federal cases.

You are entitled to the best defense strategy. You deserve to know how good and how experienced your lawyer is before you put your life into his/her hands and invest into your future. Demand specific answers to the following questions:

  • What Percentage of Your Practice Is Dedicated to Federal Criminal Defense?
  • Tell Me About the Outcome in Your Last 100 Federal Criminal Cases?
  • If I Hire Your Firm, Who Will Handle My Case?

At the end of the day it comes down to: Performance. Ask yourself: Is this the lawyer that federal prosecutors will fear and respect?

FAQs: Defending Against Federal Investigations and Criminal Charges in Oklahoma

Q: What should I do if I have received a subpoena or target letter from the DOJ or another federal law enforcement agency?

If you have received a subpoena or target letter from any federal law enforcement agency, your immediate next step should be to engage federal criminal defense counsel. Several agencies are aggressively targeting business owners, healthcare providers, and others in Oklahoma, and you will need to engage experienced defense counsel to intervene in the investigation and seek to prevent charges from being filed.

Q: What should I do if federal agents come to my home or office with (or without) a search warrant?

If federal agents show up at your home or office, your rights depend on whether they have a search warrant. If they do not have a warrant, you can (and should) politely refuse to speak with them unless and until advised otherwise by your legal counsel. If they have a warrant, you may need to allow a search to be conducted, and you should consult with an Oklahoma federal defense lawyer immediately.

Q: If I am being investigated by the federal government, can (and should) I exercise the right to remain silent?

Yes, if you are under investigation for a federal crime, you have the right to remain silent. This is a dangerous situation; and, regardless of the circumstances involved, you should rely on experienced federal defense counsel to communicate with federal agents and prosecutors on your behalf.

Q: What does it mean if I have been served with a criminal complaint?

A criminal complaint is a charging document that allows federal authorities to execute an arrest prior to seeking an indictment in the U.S. District Court for the Northern, Eastern, or Western District of Oklahoma. The DOJ has increased its use on criminal complaints in recent years, and facing a criminal complaint presents unique challenges with regard to presenting a timely and effective defense.

Q: What does it mean if I have been served with a federal grand jury subpoena?

If you have been served with a federal grand jury subpoena, this means that either: (i) you are being treated as a witness to a federal crime; or, (ii) you are being accused of a federal crime and are at risk for being prosecuted in one of Oklahoma’s federal district courts. In order to determine what you should do next, you should discuss your subpoena with a federal defense lawyer promptly.

Q: What are the potential penalties in a federal criminal case?

The potential penalties in a federal criminal case depend heavily on the specific charge (or charges) at issue. Generally speaking, however, federal crimes carry substantial penalties, and many federal criminal charges carry six-figure fines and years or decades of federal imprisonment. Loss of eligibility for government programs, loss of government contracts, and other consequences are possible as well.

Q: When is it time to hire a federal criminal defense lawyer?

Regardless of the circumstances involved, if you are under investigation by the DOJ, FBI, or any other federal agency – or if you have already been charged with a federal crime – you need to engage experienced federal defense counsel immediately. Waiting too long to engage defense counsel is a mistake, and it is a mistake from which you may never fully recover.
