Why do detectives ask the suspect how long people who committed these crimes should be convicted?
In a lot of those bodycam videos on youtube during an interrogation if the suspect is trying to say they didn't do it a lot of the times the detective will ask something along the lines of, "if we find out who really did this how long do you think they should be sentenced for." And usually they say something like life in prison.
It comes up so often that it feels like this is something they are trained to do but I dont see what affect it would have. Does it have any?
