I have had a ride along with Midwest City and Norman Police Departments this Summer. You just go to the Police Headquarters Building. Ask the Clerk behind the window for a Ride-Along form. You will have to fill it out and then get your signature notarized. Then return it to the HQ. I was called within the week. I don't know if it makes a difference that I am a Police Officer Applicant or not. With Midwest City, I could pick the shift over the form. With Norman, I had to pick the shift and date and place it on the form upon returning it. As far as getting a Ride-Along from OKC, I have been cancelled from ride alongs more than I have been able to go on. They are really busy.
On a side note, any word about when Midwest City Police will go back to the state system? When I went on the ride-along they had just gone back to UHF from the state system because of "technical isssues"
