For over 33 years, Attorney William Campbell has defended more than a thousand citizens from criminal charges in both State and Federal Courts. His firm, William H. Campbell, Attorney at Law specializes in handling all types of criminal matters, no matter how large or small.


Of course not. Why hire a State Court lawyer to handle a Federal Court case? If your case is pending in Federal Court you need a lawyer who has the knowledge and experience to immediately start to defend you. The penalties in Federal Court are as harsh as any in this country and the Federal Government intends to see that you get as much time as they can give you. Having an attorney with more than 25 years of Federal Criminal experience is a powerful weapon to have on your side. It’s your life and your freedom. Get the right experience, right now.

Attorney William Campbell attests that hard work, dedication and critical attention to detail are the foundation of every successful verdict he achieves. An example of this service philosophy was a case in which Mr. Campbell successfully got two arrests, a confession and eight and one-half ounces of cocaine thrown out due to an illegal search and seizure. In another recent case he obtained a ruling from the court determining the police had illegally obtained statements from the client and the court would not let the prosecution use the ill-gotten statements.

A Strong Defense is Important to Your Case:
Individuals convicted of a crime in Oklahoma, whether through their own admission of guilt or through the determination of a jury, are subject to, among other penalties: fines, imprisonment, probation and community service. Defending your criminal case in the strongest possible way is critical to your freedom and your future. Attorney William Campbell understands your confusion, your fear and feelings of being overwhelmed when you are arrested and charged with a crime. He understands that people make mistakes or sometimes get caught up in situations not of their making and that such conduct should not be punished so harshly.

The outcome of any criminal case depends upon the facts surrounding the crime charged, the strength of the evidence, the legal validity of law enforcement and courtroom procedure, and the goals and strategy of the government and defense. Oklahoma City Criminal Defense Attorney William Campbell will navigate you through this complicated legal process. Mr. Campbell prides himself on his record of straight talk with clients. No "false promises" --just real advice for real problems. He will tell you what you need to know, not necessarily what you would like to hear.

Attorney Profile

Mr. Campbell began his legal career when he received his Legal Intern license in 1980, while still in law school. As an intern with a highly respected Oklahoma City criminal defense lawyer, he learned the extent Federal and State Governments would go to obtain convictions. When he became a fully licensed attorney in 1982, he opened his private practice which has been in continuous operation since that time. While the practice has engaged in many areas of the law, the primary focus has been criminal defense. One aspect of the firm which this focus benefits is the ability to spot potential criminal prosecutions in matters which on the surface appear to be either civil or administrative. Mr. Campbell has made these observations on many occasions and forewarned the client of the possible criminal aspects of their case. Many of these have resulted in the filing of criminal charges which the client was, by reason of the firm's foresight, ready to defend.

The firm makes a detailed study of the facts of the case, provided first by the client, and the anticipated evidence of the prosecution, then measures those against the legal requirements as stated by the State or Federal law. Mr. Campbell believes that a strong defense is built on a position of strength not surrender. It is the policy of the firm that every criminal case accepted for representation is treated as a matter which will be tried to a jury. By taking this approach, the prosecution is presented with a resolute and determined defense intent on representing the best interests of the client. The result of such approach, has over the years, proven to be more advantageous to the client than taking a "just get me a plea bargain" approach. In cases where a plea is appropriate, the willingness to try the case will often make the prosecution more reasonable in negotiations.
