Trust
If a parent or an employee gives explicit consent, can fingerprints be used?
No; the board does not treat consent as freely given because of the power imbalance between the parties.
Detail
In the school-parent and employer-employee relationship, refusing consent carries a practical cost, so consent is not considered free.
Even where consent is obtained, the proportionality violation persists while a less intrusive method exists.
