This is why things like retention policies exist, though? Retroactively being able to query ALPR data is massively impactful to the ability to prosecute criminal wrongdoing, especially when a crime can be tied to a vehicle (such as theft of a vehicle). That utility significantly degrades with time, however!

Banning ALPRs outright is a strictly inferior solution, when compared to putting strict limits on their data retention.

This also inherently limits their potential for misuse, which seems to be your primary concern here?
