60 Minutes: Crisis in Chicago. Murders Up, Arrests Down 80%. ACLU Has an Effect on The Chicago Police Department.

60 Minutes reports:

we were astonished by data we obtained from inside the police department. It revealed that as killings rose, police activity fell. In August of 2015, cops stopped and questioned 49,257 people. A year later those stops dropped to 8,859, down 80 percent. At the same time arrests were off by a third, from just over 10,000 to 6,900.

A video report, well worth your time.
