LOLWUT?
I've seen 3 episodes of 24 and not 1 had an interrogation scene
I don't want to waste my money so I'd appreciate it if you could be more specific with regards to episodes.
You've seen 3 episodes? Get watching 24 dude!

Like I said, I can't remember exactly which seasons and episodes where every interrogation is.
I remember the one in Season 4, think it was Episode 2. Jack worked for the DoD and had to go to CTU. CTU at the time were trying to interrogate a terrorist and were getting no where.
So Jack, being Jack decides to knock out the security at the holding room door, take his gun and interrogate the terrorist himself. The terrorist refuses so Jack just shoots him in the kneecap.
All the scenes end up like that one way or another, but they are the most impressive/realistic interrogations I have seen and enjoy watching.
But, your interrogation is along the lines of day to day police work, so might not suit the needs you have.
