The Michigan chapter of the American Civil Liberties Union is questioning the need and use of the data obtained by the Michigan State Police.

The Michigan State Police are asking for drivers to hand over their cellphones, this the ACLU contends is a breach of the 4th Amendment rights.

The ACLU filed a Freedom of Information Act (FOIA) pretaining to the use of the devices by the Michigan State Police. The MSP said it would work in accordance to the FOIA in return for 500,000 dollars.
