According to a new state law signed today, it's now illegal to lie or conceal facts from Michigan police officers who are investigating a crime.
The law says people do not give up their right to remain silent, but if they do talk, they have to tell the truth.
Sergeant Dwayne Gill is with the Michigan State Police.
“This law kind of mirrors the federal law on lying to federal agents. When we’re interviewing individuals, it’s a tool that law enforcement can use to elicit the truth in investigating crimes.”
The American Civil Liberties Union says the law appears to be constitutional.
But a spokesperson says the ACLU is concerned about unintended consequences -- such as people not reporting crimes, or witnesses who refuse to cooperate with authorities because they’re afraid of being charged if they make a mistake.
