lies

What happens if I lie to police?

The reason you should avoid lying to police is the same reason you should avoid talking to police. (See "If I'm innocent, should I talk to police?")

Whether or not you have information that could incriminate you or others, you should resist the urge to try to talk yourself out of a situation and try to remain silent instead. Police may not hold your silence against you as evidence of guilt.

Police are generally good at detecting lies, and getting caught in a lie may give an officer more justification to detain you. Regardless, if police are questioning you, you are probably considered a suspect and -- depending upon the situation -- you should be prepared to assert your rights by a) refusing search requests ("Officer, I don't consent to any searches."), b) determining if you are free to go ("Officer, am I free to go?"), and c) remaining silent until you see a lawyer ("I'm going to remain silent. I want to see a lawyer.").

Are police allowed to lie to me?

Yes. It's a legally accepted -- and highly effective -- interrogation technique to lie to you and present false evidence in order to elicit a confession. This is particularly common during interrogations in which officers might tell you that "your friend already gave you up, so you might as well come clean."

The best defense against these manipulative tricks is to avoid saying anything to police without first speaking with an attorney. Use the magic words "I'm going to remain silent. I would like to see a lawyer." Repeat, if necessary.
