Is it a crime to refuse to give information?

No.

 

If the police are conducting a criminal investigation and you are the ‘person of interest’ it is not a violation of law to withhold information that can incriminate you.

 

If there is any concern in your mind that you may somehow be drawn into their investigation and become a “person of interest” then refuse to answer any questions.

 

Demand the right to have an attorney present at any questioning.

 

If you have nothing to hide then you have nothing you need to tell the police.
