Not everyone has gone to jail, but if the govt has your fingerprints it’s easier to get convicted regardless of your innocence.

Clear Blue is like this, but they use your iris scan. You have to scan every time to skip the line. But the TSA precheck just fingerprints you once when you sign up IIRC

e.g. Period tracking apps being used as evidence when prosecuting people who seek abortions

A lot of people have just accepted surviellance for convienience.

People close to me get TSA precheck even though it requires fingerprinting, because “the government already has your fingerprints”

But if they did, why would they need to ask your for them?
