Kansas City Criminal Defense Firm

Aggressively Defending the Accused Since 2002

While laws exist to keep us safe, the criminal justice system is inherently stacked against defendants. Whether you were unaware of your actions, lost yourself in a heated moment, or simply made an honest mistake, don’t let a criminal charge define the rest of your life. At Benjamin Law Firm, LLC, we provide fierce advocacy to safeguard your freedom and future. 

Our criminal defense lawyers understand how overwhelming and isolating it can be to feel like the entire world is turned against you. Regardless of the charge you’re facing, you deserve to be treated with respect and dignity. Our firm takes the weight off your shoulders by scrutinizing every piece of evidence and presenting a compelling, strategic defense that protects your life and livelihood.

If you’re accused of a crime, put an award-winning criminal defense firm on your side. Call (816) 323-3460 to schedule a consultation. We serve clients in both Kansas and Missouri. 

A Trial-Ready Defense Team Built for High-Stakes Battles

We believe that every defendant deserves the best possible representation. A strong defense requires an in-depth knowledge of criminal law, including what elements are required to secure a conviction and how prosecutors build their cases. As a former public defender, our founding attorney deeply understands the inner workings of the criminal justice system. We never shy away from difficult or high-profile cases and approach every charge with a trial-ready mindset to position your case for a favorable outcome from the outset. 

Why You Need Fierce Representation from Our Defense Lawyers

Whether you’re already facing charges or currently under investigation, being accused of a crime can have lasting impacts on your life. Even if you're innocent or intend to plead guilty, working with our seasoned defense lawyers is paramount to avoiding the life-altering consequences of a conviction. 

No matter the severity of the offense, we are dedicated to advocating for an outcome that preserves your liberty. We understand how the state approaches criminal cases and fight tirelessly to hold investigators and prosecutors accountable for meeting the high burden of proof in criminal proceedings. 

When the System Isn’t Fair, We Fight Back We offer a No-Obligation Consultation with a member of our team to discuss the benefits of working with our firm.

  • Criminal Defense
  • Domestic Violence

How We Level the Playing Field for Our Clients

When you’re accused of a serious crime, any attorney won’t do. It’s important to hire a lawyer who is knowledgeable about your specific charges and has a strong track record of success to prove it. The prosecution utilizes vast resources and personnel focused solely on building a case against you, making it critical to choose a firm that is capable of matching the state’s firepower. 

Our attorneys leverage decades of experience to pursue fair resolutions for clients accused of a wide range of allegations, from high-stakes sex crimes and murder charges to DWI and traffic offenses. We refuse to let the state dictate your future without a fight. By conducting independent investigations and engaging in rigorous preparation from day one, we work to neutralize the state’s advantage and level the playing field for our clients.

HAVE QUESTIONS?

We Have Answers.
  • What Should Your First Steps Be After an Arrest?

    After you’ve been arrested for a crime, your first step should be to contact a criminal defense attorney who has experience with your charges. Whether you’ve been arrested for DWI or are being charged with a serious violent crime, you need legal representation through every part of the process. Once you have notified the investigators that you wish to speak with an attorney, don’t answer any questions. If you make a phone call to a family member or friend, don’t discuss any details of the case or explain what happened to avoid having these statements used against you in court.

  • What Rights Do Defendants Have in Missouri?

    Defendants who have been charged with crimes in Missouri have a variety of rights. Some of the most important include the right to remain silent so that you don’t incriminate yourself while answering questions, the right to have a defense attorney even if you can’t afford one, and the right to due process. Other rights that often come up in these cases include the right not to be subjected to illegal search and seizure and the right to a speedy trial before a jury of your peers.

  • Will I Be Charged With a Misdemeanor or a Felony?

    Under Missouri law, most criminal charges are either misdemeanors or felonies. Within those two categories are different classes, depending on the severity of the offense. Some crimes, such as murder, are always felonies, while others, such as DWI, can be charged as either a misdemeanor or a felony. In this example, a first offense is a misdemeanor, but a third or subsequent offense is a felony. Your charges will depend on the type of offense, whether you have any previous similar criminal convictions, and whether there are any aggravating factors. In some cases, an attorney can help you get your charges reduced from a felony to a misdemeanor.

  • Is a Plea Bargain an Option?

    Plea bargains are a way for the defendant to get a lesser charge or a lesser penalty and for the prosecution to secure a conviction and avoid the time and expense of a trial. They can be beneficial in some situations where the evidence is strong or the charges are very serious, such as with a Class A or Class B felony. Criminal defense attorneys are able to negotiate with the prosecution to work out a deal that is the most favorable outcome possible for their clients. However, a plea bargain is not an option — or the best option — in every case and is never guaranteed.

  • What Are My Defense Options?

    No matter what criminal charges you face, you have the right to a strong defense. The strategies and options that are the best choice for your situation depend on your charges and the surrounding circumstances. A criminal defense attorney has the knowledge and skills to determine which option offers the highest likelihood of a favorable outcome, and they can explain to you the reasons behind their advice and the pros and cons of each choice. In general, you will have the option to plead guilty, plead not guilty and fight the charges during a criminal trial, or negotiate a plea deal.

  • Is It Possible to Have a Conviction Expunged?

    Missouri law does allow for some convictions to be expunged, but there are specific parameters around which charges can be expunged and who is eligible. In general, Missouri law allows you to expunge up to two felony offenses and three misdemeanor offenses over your lifetime, and offenses committed as part of the same course of criminal conduct can be counted together. Once you reach those limits, you will not be able to expunge additional offenses of that type. Your charge must qualify for expungement — violent crimes and other serious charges may not be eligible — and you must have completed your entire sentence, including paying fines and restitution, then waited the required period (generally three years for a felony and one year for a misdemeanor) without a new conviction. Intoxication-related driving offenses are handled differently from most other offenses. Missouri has a separate expungement process for certain DWI offenses, and eligibility depends on your record and how much time has passed.

    Missouri also recently passed a law that will automatically expunge certain eligible, nonviolent offenses without a petition once the state’s system is operational. Offenses that do not qualify must still go through the court petition process.

  • What Should I Do If I Was Falsely Accused?

    Being accused of a crime when you’re innocent can be extremely distressing. Many people believe that if they are innocent and just tell the truth that the criminal justice system will serve its purpose and the charges will be dropped or they will be acquitted. However, there are thousands of innocent people serving time right now in jails and prisons across the country. Even if you’re innocent, it’s important to immediately hire a criminal defense attorney to represent you and ensure your rights are protected. Don’t talk to police or try to offer evidence or a statement to prove you’re innocent. Your attorney will handle all of these pieces and ensure that you have legal guidance and counsel every step of the way.
