This is why you do not talk to police.

One time j lied to a policeman and then he searched my car. A second time I said no and he searched me because I lied last time.

Do you understand the difference between not talking to a policeman and lying to them? Hint: to do one you have to actually talk to them.

Provide your ID, tell them you don't answer questions, and then completely shut up. Do not lie to the cops, do not be disrespectful to them, just don't talk to them.
