It could be used to scan people's heart rates when they're in a high security line (military check points, airports, embassies) to detect people who are nervous.

I assume some places already use thermal cameras to detect people who are sweating profusely.

Using both together might be a decent way of flagging people who might otherwise slip through security.

Of course there would be many false positives, so it wouldn't be good enough on its own.

That is the same excuse cops regularly use to violate peoples rights and justify illegal searches and stops or claim they are impaired when they aren't. The very fact that people are being closely watched or monitored is in itself a reason for people to be nervous.
Yes, some people will be stressed and nervous for benign reasons. Criminals will also be stressed and nervous.

A good security system will use multiple signals to filter out false-positives.

Yep, that's definitely what we need more of right now, not less.
What's the objection? I don't see how having my heart rate scanned at an airport or military checkpoint in any way impinges on my freedom or happiness.
Please supply your dna and biometrics at every entry point of a public roadways. Thank you good citizen.

Hysterical slipper slope nonsense.

Using RF to passively detect someone's heart rate at close range is objectively less intrusive than cameras are.

Right up until they take you aside for body crevice analysis because your heart rate was a little high, anyway
Doesn't seem like a reasonable objection to me. It takes a lot of time and man power to search people's body cavities. The incentive is to avoid searching as many people as possible.

Oh good lord. Now it's no longer even "have you read a history book on the 20th century?" anymore, it's "have you been paying attention to the world for the past 15 years?".

Spare me the hysterics and the insults. What exactly is your claim?

That body cavity searches have increased rapidly over the last 15 years? That it's a common occurrence? That security personnel actually has an incentive to do them more rather than less?

Give me the books you read and sources you read that support your claim. I doubt they exist. I suspect you're going off "vibes" here, but I'll gladly read them if you can cite them.

True. To avoid searching as many of the wrong people as possible, and search all of the right people. Of course, those categories are fluid.

Today you’re among the people to avoid searching; tomorrow, well… maybe you’ll have a reason to be nervous.

> Today you’re among the people to avoid searching; tomorrow, well… maybe you’ll have a reason to be nervous.

What do you even mean here? Seems entirely incoherent.

You're missing the point: if the computer picks you out for some reason (perhaps you are ill, perhaps you are worried about losing your job or a family member's health, whatever), they won't care about the economic inefficiency or the infringement on your rights. Just because you don't intend to commit crimes doesn't mean you're immunized from bad decision-making by security systems.
Explain how it's worse than a camera or thermal camera that detects you sweating? Explain how it increases the incentive to do body cavity searches?
Because having a high heart rate doesn't mean you've committed a crime. Are you trolling?
"Of course there would be many false positives, so it wouldn't be good enough on its own."
Going through airport security is stressful and unpleasant already with a lot of people whose heart rates are probably somewhat elevated as a result.
"Of course there would be many false positives, so it wouldn't be good enough on its own."
Unless something about you is targeted to increase searches to intentionally inconvenience people like you. Then it just becomes parallel construction.
Dubious utility aside, this is a solved problem using mmWave.

Google even ships it in some Nest displays for sleep tracking...

Wifi seems much more capable and harder to defeat? A heavy coat could defeat mmWave, I believe.
