When police lights flash behind you or an officer approaches you with questions, even the calmest person can panic. In those stressful moments, your words can either protect you—or legally hurt you.
That’s why understanding how to avoid self-incrimination is not just useful; it is critical. Most people unknowingly give police information that later becomes evidence against them.
This guide explains exactly what NOT to say to police, why silence is legal and protected, and how to handle any police interaction in California—especially in San Francisco, where arrests related to DUI, assault, theft, and drug charges occur frequently.
Hallinan Law Firm has defended thousands of clients who said the wrong thing at the wrong time. This article is designed to ensure you’re never one of them.

Why Your Words Can Be Used Against You
Police officers are legally trained to gather statements that can support their investigation. Even casual conversation like:
- “I only had two drinks”
- “I was just driving home”
- “I didn’t mean to do anything wrong”
These lines seem harmless, but in court, they become powerful evidence.
Under the Fifth Amendment, you have the right to remain silent. Exercising this right is not suspicious, rude, or dangerous—it is smart.
Most people incriminate themselves because they believe:
- Staying silent looks guilty
- Cooperating will make the officer “go easy”
- Explaining their side quickly will solve the issue
All of these assumptions are false.
Police are trained to interpret your words in the least favorable way.
What NOT to Say to Police (Most Common Mistakes)
Below are the most dangerous statements people make during police interactions. Avoid these at all costs.
1. “I didn’t do anything wrong.”
This sounds innocent, but it can backfire.
Why?
Because the officer may respond with:
“Then tell me what happened.”
That “story” becomes evidence.
It is better to say:
👉 “I am choosing to remain silent. I want a lawyer.”
2. “I only had a little bit to drink.”
In DUI cases, this is the most damaging line people speak.
Confessing to “any” consumption gives police:
✔ Reasonable suspicion
✔ Probable cause for tests
✔ A statement they can use in court
Even admitting to one drink is enough.
Say nothing about alcohol.
3. “Yes, you can search my car/phone.”
NEVER consent to a search—ever.
Once you consent, your defense becomes harder because:
- Evidence found is automatically “valid”
- Your lawyer cannot challenge the search
- Police gain full access to your private belongings
Simply say:
👉 “I do not consent to any searches.”
This is 100% legal.
4. “I’ll answer your questions, but I don’t want trouble.”
This tells police:
- You’re nervous
- You’re willing to talk
- You might reveal something unintentionally
Police are skilled in asking questions that feel friendly but are designed to trap you.
Silence is safer.
5. “I swear, I’m telling the truth.”
People say this when they feel pressured.
But legally, “swearing” means nothing.
Instead, it can signal:
- Panic
- Fear
- Guilt
Stay calm and repeat your right to silence.
6. “I didn’t mean to do it.”
This is a partial confession.
Even if you are innocent, statements like this imply you did something.
In court, “I didn’t mean to” becomes an admission.
Never say this—even accidentally.
7. “I’m sorry.”
Apologizing equals taking blame.
Examples:
“I’m sorry, I wasn’t paying attention.”
“I’m sorry if I caused a problem.”
This can be twisted into an admission of guilt.
8. “I’ll explain everything.”
No matter how confident you feel, this creates danger.
Explaining means:
- You fill in details
- Police connect the dots
- Your timeline gets examined
- Your words get documented
Explanations are the #1 source of self-incrimination.
9. “Go ahead, check it. I have nothing to hide.”
Again, never consent to searches.
Even if everything is clean, something as small as:
- An old prescription
- A friend’s item
- A misunderstood message
- A damaged taillight
- Passenger belongings
…can unexpectedly become legal trouble.
Why You Should NOT Answer Police Questions Without a Lawyer
You are not required to answer questions other than providing:
- Your full name
- Your ID (in specific situations)
- Basic identification details
Everything else is optional.
Police may say:
- “We just want to clear your name.”
- “Help us understand what happened.”
- “You’re not in trouble—just talk to us.”
These are investigative strategies.
A lawyer’s job is to protect your rights FIRST, not help the police build a case.
How to Assert Your Rights (Without Sounding Aggressive)
You can protect yourself and still remain respectful.
Use this simple script:
“I am choosing to remain silent. I would like to speak with my attorney.”
“I do not consent to any searches.”
Say it calmly.
Say it clearly.
Say nothing more.
Your Rights When Detained or Arrested in California
Police MUST follow specific procedures. In California:
You have the right to:
✔ Remain silent
✔ Ask for an attorney
✔ Refuse consent for searches
✔ Know why you are being detained
✔ Decline to answer questions
You are NOT required to:
❌ Explain your actions
❌ Admit to anything
❌ Share where you are coming from or going
❌ Disclose if you drank alcohol
❌ Give your phone passcode
These rights are powerful.
Use them wisely.
How People Accidentally Incriminate Themselves (Without Realizing It)
• Oversharing
Talking too much = giving too much evidence.
• Trying to “clear everything up”
Police are trained to extract confession-style statements.
• Assuming honesty will make the officer lenient
Officers do not decide guilt. Judges do.
• Attempting to act “helpful”
You cannot talk your way out of an arrest.
• Trying to sound innocent
People often contradict themselves under pressure.
What to Say Instead (Safe Legal Phrases)
Use these exact sentences:
1. “Am I being detained or am I free to leave?”
This forces the officer to clarify your situation.
2. “I am exercising my right to remain silent.”
3. “I want to speak to my attorney before answering questions.”
4. “I do not consent to any searches.”
(Say this even if a search still happens.)
5. “I would like your badge number.”
6. “I do not wish to make any statements.”
These phrases protect you legally.
How Police Try to Make You Talk (Common Tactics)
Police often use psychological techniques such as:
✔ “We already know what happened.”
Not true. They want you to fill in the gaps.
✔ “Your friend already told us everything.”
Also commonly untrue.
✔ “Talking will help you.”
Talking helps them, not you.
✔ “Only guilty people stay silent.”
Legally incorrect and manipulative.
✔ “We want your side of the story.”
Your silence is your protection.
The Biggest Myth: Staying Silent Makes You Look Guilty
This is false.
Courts cannot punish you for silence.
Juries cannot assume guilt.
Police cannot force conversation.
Silence is your legal shield.
When You SHOULD Speak to Police
There are very few situations where you must speak:
- To identify yourself
- To provide your license (if driving)
- To share registration and insurance
That’s it.
Anything beyond that is optional.
What If the Police Threaten You With Arrest?
Stay calm.
If you are going to be arrested:
- Talking will NOT prevent it
- Explaining will NOT stop it
- Cooperating verbally will NOT change it
But staying silent will protect your legal defense later.
