It was in an anthology, and I believe it was a kind of sci-fi detective story. The premise was that teleportation (or something like it) was possible, but there had to be an equivalent mass in another booth (?) to balance the person being transported. The balancing individual would essentially explode (or something similarly gruesome), and so condemned criminals were used for this purpose.
The narrator was some kind of law enforcement personnel, who has a negative reaction when a colleague from another city chooses to travel this way, even though the situation is not an emergency.
