It doesn’t get you anywhere calling people names.
I was reading a book on forensic sciences. The police were questioning a suspect on a grisly murder of a child. One officer was kind to the suspect, calling him sir or mister. At his own expense, he purchased a KFC meal for both of them and sat down and ate with him. Shortly after the meal, the suspect confessed all. The officer later asked why he confessed? The suspect explained that the officer was the only one who EVER treated him kindly.
There is no reason to be cruel and abusive. We should be kind all the way up until and including throwing that switch. Calling names dehumanizes and makes inhumane treatment easier. That is why soldiers use terms like Japs, Krauts, Nips, etc., dehumanize, easier to kill. I work with livestock. I always try to speak or think kindly even when they are bad. You have to be a pretty big sicko to beat on something you call babe, pal, friend.
Waitaminnit... Japs AND Nips?! No Dagos? Dissing the Italian portion of the Axis, are we?
What names do you suppose the Japanese pilots were calling the inhabitants of Pearl Harbor during their attack?
Who was the old warrior who liked to be called America’s most decorated soldier. The name escapes me but I read his book years ago and he claimed as much. He said when he got a captured NVA or VC he would sit them down, give them a cigarette, a bowl of ice cream. In fifteen minutes they would tell him everything.
I knew a deputy that was pretty good at getting confessions. They’d put a guy in the small concrete block building where they did interviews, they guy would be scared to death he was about to meet a rubber hose, and the cop would ask the guy if he wanted a snack or a soft drink, and make a pretty big deal of digging change out of his own pocket to buy the guy a candy bar and canned drink from the vending machines that were located in the building.
While good cop/bad cop isn’t a bad tactic, it’s the good cop that will get the confession. And frequently, the bad cop isn’t even needed.
