Jon Katz knows how to challenge these prosecutions at every level. He questions whether the police had a legal basis to stop your car, whether field sobriety tests were administered correctly, and whether breath or blood test results were accurate, admissible, or even obtained legally.

Drug Charge Defense Lawyer in Leesburg

Drug charges, whether for possession or distribution, can leave a permanent stain on your record. Jon Katz defends against all types of Leesburg drug prosecutions, including marijuana, cocaine, heroin, prescription pills, and alleged trafficking. From the very beginning of the case, Jon challenges the legality of the stop, the search, and the seizure. He scrutinizes the reliability of the drug evidence, exposes flaws in the lab testing process, and seeks to suppress evidence that should never have been collected in the first place.

He also challenges whether the prosecution can truly show that you had knowledge, dominion, or control over the drugs.

Leesburg Assault and Violent Crime Defense Lawyer

When charged with assault or another violent offense in Leesburg, the stakes are high. It’s not unusual for the person who started the altercation to rush to the magistrate first, leaving the true victim facing criminal charges. Prosecutors don’t have magical powers to tell who is telling the truth. That’s why you need an assault defense lawyer who knows how to present your side of the story clearly and powerfully, and who will not allow you to be railroaded by a system that too often gets it wrong.

Jon Katz works closely with clients to prepare compelling self-defense arguments, expose false or exaggerated claims, and bring forward any evidence that proves innocence, mistake, or mutual combat. Whether the incident involved a stranger, a family member, or an acquaintance, Jon makes sure your defense is built for trial and that the jury hears the full truth, not just the government’s version of it.

Firearms and Weapons Offenses in Leesburg

Virginia has a complicated and often harsh approach to firearm and weapons offenses. Jon Katz defends clients charged with crimes such as felon in possession of a firearm, carrying a concealed weapon without a permit, and possession of a firearm in connection with a drug offense. These are serious cases, and a conviction can lead to years in prison.

Jon focuses on challenging the government’s evidence and the underlying police conduct, questioning whether law enforcement had any legal basis to stop you, search your vehicle or home, or seize your weapon. He also contests whether the prosecution can prove you knowingly possessed the weapon in the first place. With a deep knowledge of Second Amendment protections, Jon pushes back hard against unlawful searches and unreliable evidence.

Sex Crime and Rape Defense Attorney in Leesburg

Few charges carry more stigma than a sex offense. The mere allegation can lead to job loss, social isolation, and even pretrial detention. Jon Katz understands how high the stakes are, and he treats these cases with both discretion and strength. Whether you’re charged with indecent exposure, sexual battery, rape, or possession of unlawful material, Jon approaches the case with a focus on thorough evidence review, constitutional rights, and courtroom preparation.

In sex cases, the law often presumes guilt long before the facts come out. Jon fights back by challenging the credibility of witnesses, pushing for full disclosure of exculpatory evidence, and, when needed, working with mental health experts to provide mitigating information. His goal is to avoid conviction altogether, but when that’s not possible, he does everything in his power to minimize the damage.

Homicide and Manslaughter Charges in Leesburg

Being charged with murder or manslaughter is devastating. Jon Katz knows that your future may depend on the smallest detail in the evidence or testimony.

He knows how to challenge faulty narratives, unreliable codefendant statements, and incomplete police investigations.

With decades of experience defending the most serious cases, Jon stands ready to fight for your life and your freedom. Whether you’re accused of first-degree murder or involuntary manslaughter, you will have a lawyer who is in your corner and ready for battle.

I contacted Jon due to an extreme number of positive reviews online after receiving a Felony possession of Marijuana w/ Intent to Distribute charge. To be very clear, I'm a family man with a career and don't sell Mary J. I knew he cared about beating this case after just 10 minutes of talking to him, oh and don't interrupt. During the middle of our first meeting I shared that a week prior i got a reckless driving charge and had a pending petty charge from my child's Mother. I presented Jon with 2 misdemeanors and 1 felony. Go Time Listen, focus, execute is what I learned from doing Jon's Homework, do the homework! Jon truly is a master a his craft and his staff is outstanding as well, Lori was terrific. He works extremely hard and dazzles in the courtroom with his knowledge of the law and court system. I must say that Jon truly helped my life in every way possible and I would recommend and have recommended Mr. Katz to anyone who needs an attorney for legal troubles. All 3 charges NOLLE PROSSED, you the man, Jon let's keep in touch !

I stumbled into a misdemeanor charge; I responded immaturely to an act of aggression. My guilt was not in question, so understand there was only so much a lawyer could do for me. I had no experience with court and had no idea what to do or expect, so I turned to a law office I found on the web only to walk out more depressed after their gloomy outlook, Jail. It was a foreign cold dismissive experience talking to them, and I left wondering what have I done. My immaturity has put my future in their hands? I, fortunately even though I had little time, decided to continue looking and discovered Mr. Jon Katz. Jon, from the first meeting until our last contact, has a sympathetic warm way about him that engenders confidence. From the first meeting he focused on a method that not only developed his thorough interpretation of the event that led to my arrest but also with a focus on me, the human in difficulty. For some, that appreciation or sympathy may not matter, but it did to me. Jon's method and candor helped me settle down and coup as I was depressed, unsure, and yes, scared. There are things suddenly on the plate to take care of when confronting a court case and Jon, and his staff, professionally promptly handle the court scheduling and documentation expectations/demands so all that potential stress is absorbed by them. But most importantly, it was Jon's court savvy and experience that lead to a lesser charge. I was convicted as that was a given going in, but the punishment was community service not jail and for that I have Mr. Jon Katz to Thank. The last impression I choose to share is that Jon is driven, committed; Jon is a hard working determined legal mind. Mr. Jon Katz, and his prompt helpful staff, can help you prepare for and confront the court experience competently and confidently. Richard B.

Last year i was charged with a felony drug case. I met with Mr. Katz shortly after while searching for an attorney i felt would put in the work and go to bat for me. I had a couple bad previous experiences with lawyers in the past, but I quickly realized Jon was the lawyer for me. Mr. Katz was direct, knowledgeable, and took charge of the meeting in a way that gave me the feeling he was not easily pushed around in court. My case was put off multiple times, but Jon always kept me in the loop and ALWAYS responded quickly to my emails. In the end Jon was able to get my case dismissed entirely. Our family can't thank Mr. Katz enough. If you are looking for a lawyer that will truly fight for you, hire this man. while other lawyers are goofing off. Jon is in the books searching for new ways to defend his next client.

"thorough " would be my word in describing attorney Jon Katz....never misses a beat every step of the case. Starting with the arrest and miranda rights, Jon examines every aspect of the case. Especially important in d.u.i. cases is the breath results which Jon examines in detail finding any procedural flaws that might happen. Jon engages the prosecution like a samurai warrior in that he can absorb their attacks, and yet offer brilliant strategies in a calm manner. His years in court offer a perspective about the judge, jury and prosecution that are of priceless importance when mounting a defense. His daily blog on facebook is a great way to experience real life court . I would highly recommend this attorney for all legal matters.

I would like to share that I had a DUI on 10/11/2021. I just saw his reviews and called right away to him. Not only he accepted my case happily, but the way he talked to me was hilarious and hiller. I had the court date on the 17th of February 2022 and he did unbelievable job. My case dropped from DUI to Improper driving control. That was awesome and always thanks to him.
