As someone deeply interested in the tech used behind this stuff, this is absolutely a terrible idea that only allows an excuse to harass people without actual reason.
Even if there wasn't the same behaviour and sordid history with mind reading tactics based around the cop feeling "something is off" which, funny enough, happens to trigger when dealing with people of different culture or neurotype.
Now the technology being used famously has a problem with low data samples, which would also translate into "minority groups."
This isn't "evil technology," it's evil opportunists that found an opportunity, using a tool for something we know isn't robust enough for such serious context.
If it's weren't AI it would be the charlatans around mind reading and micro expressions.
We need accountability for those with power who use said power maliciously or deceptively.
And beyond that, we all need a focus on the 1984 behaviour, as there is a weird global fascist push to protect the current power structure.
