Here's a really great video produced by the Ford Motor Company, showing the Michigan State Police in 1957. Starting at the 13:00 mark, there is a bank robbery that takes place in Oakland County. Doesn't anyone recognize where the bank was located at? Likewise, you have a chance to see a lot of the two-way radio equipment in use at that time.
