Does anyone ever actually use that line? Most people will argue that the trade off in privacy is worth it for security.

That is, if you frame your argument such that you believe people don’t understand the trade off it allows you to not engage with the fact they just disagree with your conclusion.

Have you ever sat on a jury in a criminal case? A frighteningly high percentage of people will swallow every lie a cop tells, even when thoroughly discredited in cross-examination. There's no shortage of people to guard the concentration camps.

I was on a jury a few years ago. The defendent was a homeless person with mental health issues. The cop was obviously lying about the one thing that was the core element of the crime. It was like a child telling the truth about every element of the indoor soccer game expect the part where they were the one who kicked the ball.

The jury was me, (white) nine other white people, and two brown people. Me and the brown people thought the cop was obviously lying, and was therefore not guilty. The nine other people thought he was guilty.

Like the cop was obviously fucking lying.

After three days of deliberation we declared a hung jury.

I was speaking with the prosecutor afterwards and he mentioned they were going for the felony version of the crime instead of the misdemeanor (he was obviously guilty of the misdemeanor, the felony depended on the element the cop was lying about) because the dude was a bad dude and they needed to get him.

I looked him up when I got home. (I didn't look him up during the trial, they expressly forbid you from doing that) He had done something bad and went to prison for four years. He did his time and got out. They were still trying to throw the book at him for bullshit.

I looked him up recently. He was never convicted of anything ever again, but died in jail two years after we declared a hung jury. Prosecutor got what he wanted in the end, I suppose.

Why is complying with that rule more sensible than believing the cop because he's a cop?

Because it is a well documented source of bias.
