Police could focus on better using the data it already has. Rather than giving it the power to hoard more personal data and endangering public liberties.

Existing police record are riddled with errors:

• propublica.org/…/politic-il-insider-chicago-gang-…
• lesnumeriques.com/…/alerte-cnil-trop-erreurs-dans…

Piling more data on top won’t fix these errors. Putting more effort in fixing errors would make the records more useful to police, and would probably avoid ruining the lives of innocents people.
