You're literally denouncing the 4th amendment. You're saying that all of us must submit to warrantless and broad searches because the statistics says that at least some crime must be occurring. Absurd.

Most people aren’t doing crimes. Roads are used to traffic drugs but we don’t hold the state accountable nor do we setup checkpoints within country to inspect cars for illegal material because some % of cars do.
If your point is that privacy advocates aren’t considering the negative aspects of technology I’m sure they have but see these efforts as a reach towards more state surveillance.
