What I did was downloaded the map, right-clicked it, and clicked "EDIT", so it would open in PAINT....That way, I could "circle" the ones I knew for sure I got, as I got them....
Please note: I used this map to get most of them on my easy playthrough but accidentally deleted my save before I could finish and had to start over on Normal so I can get NG+.......that is the only reason I don't have this cheevo yet....I used this same map when I got this cheevo on the 360 version......
Hope this helps!
Edit: Unlocked when done again in NG+. Also worth pointing out that post end game, these appeared to be always on everywhere rather than random. Maybe I got very lucky but I wouldn't sweat getting it early if you plan on completing the story.
One of the side missions involves beating up thugs who are bullying political prisoners in Arkham City. These are unmarked on the map and only appear when you get close in proximity to them. Once they are triggered, you will see and hear a “Local Surveillance” notification on-screen, with an audio clip of the thug and the prisoner. That side mission will then appear on the map as a pulsing white hexagon.
There are sixteen of these total. Most are in The Bowery and Park Row, with some being in Industrial District. None are in Amusement Mile. One of these is Jack Ryder, who is being beaten up before the Courthouse sequence. If you do not rescue him, a generic political prisoner will replace him in a different location.
The easiest way to find them is to use Detective Mode (, on PS3) to clearly see them through walls. Refer to the map below for their locations, marked in Yellow. Jack Ryder is marked with “JR”, while his replacement is marked with “Rp.”
