What to Do After You’re Arrested in O’Fallon, MO
Being arrested in O’Fallon, MO can be an overwhelming and intimidating experience. Whether it’s your first encounter with the criminal justice system or not, what you do in the moments immediately following your arrest can greatly influence the outcome of your case. Follow these critical steps to protect your rights and strengthen your defense from the very beginning:
Step 1: Keep Calm and Avoid Resistance
Even if you believe the arrest is unfair, do not argue or resist. Resisting arrest in the O’Fallon, MO area, even verbally, can result in additional charges and make your situation worse. Stay calm, keep your hands visible, and comply with police instructions. Everything you say or do will be closely observed and may later be used against you in court.
Step 2: Stay Silent and Ask for an Attorney
The U.S. Constitution protects your right to remain silent, and it’s one of your most powerful legal tools. After confirming your identity, you are under no obligation to answer questions about the alleged offense. Politely state: “I am exercising my right to remain silent and would like to speak with my attorney.” Do not attempt to explain or defend yourself; even innocent remarks can be misinterpreted and used against you in court.
Step 3: Ask for a O’Fallon, MO Criminal Defense Attorney Immediately

This is your constitutional right, and invoking it is one of the most important decisions you can make.

- We’re available 24/7 to respond to emergencies anywhere in O’Fallon, MO.
Step 4: Avoid Discussing Your O’Fallon, MO Case with Anyone
Don’t discuss your arrest or charges with anyone but your attorney. Conversations with friends, coworkers, or even family members can be misinterpreted, and anything shared on social media can be used against you. Prosecutors can subpoena texts, posts, and messages. To protect your defense, keep quiet and let your legal team at Combs Waterkotte handle all communications on your behalf.
Step 5: Refuse Searches Without a Warrant
Police may ask to look through your phone, your car, or even your home—but unless they show a legitimate warrant, you can and should say no. Politely respond, “I don’t consent to any searches.” You have every right to protect your privacy and property from unlawful investigation in the O’Fallon, MO area.
Unlawful or warrantless searches often lead to suppressed evidence, meaning it cannot be used against you in court.
Step 6: Secure Bail or Release

- File motions to lower your bond amount
- Advocate for release pending trial
- Work directly with bail bondsmen to secure your release fast

Not always. Missouri allows for expungement of certain crimes after a waiting period. Our O’Fallon, MO criminal defense attorneys can determine if you qualify for expungement and help clear your record.
