Since the experience is still fresh in my mind, here's how the Jamaican police certificate works:
1. Go to the North Towers at Oxford Road, take a right when you get in the lobby. Ask one of the nice policemen at the desk for a form to get your police records (take your own pen, for heaven's sake, don't depend on the one they give you to be working). Fill out the form, present your ID and TRN and payment to the cashier, receive your receipt, ID and TRN and exit the building.
2. If you are going to Duke St. same day, good luck. The line starts forming around 7:00 a.m., so by the time you get there, they might have stopped giving people numbers!
3. Go to Duke St. VERY early one morning, go inside and get a number before 8 a.m. Make sure you have your receipt and your ID, you will need these to be given a number to wait in line. If there is something else you can do while you wait, do so, otherwise, prepare to amuse yourself with the antics of the other people and the very rude police personnel. Take an umbrella, the space inside is very limited and you may have to stand outside for a time, and there is no shade.
4. Wait in line for your number to move slowly inside until you get to the inner room, where you will be given forms to fill out. Remember to have your ID and a pen.
5. Wait some more, you will finally hear "next!" at which point you go in, have your fingerprints and mugshot taken, hopefully not by the rude technician who couldn't spell my name even though it was all over the forms and my ID which she had in her hand. When you are finished, you will be sent upstairs to wait some more, they will call your name, and return your receipt to you with the date when you can come back to collect the record.
6. By this time, it should be about noon, go home and lie down and recover.
7. The collection hours are 12:30 to 3:30, ensure you arrive promptly. You will be told to wait outside in the sun, where every now and again, someone will come out with a few records in hand, call the names, and you have to say "present" then push and shove until you reach close enough to take your record from the officer.
8. Go home, lie down and recover.
