Rayiner, you are supposedly adept with constitutional law.
The state is not allowed to pursue every physically possible means of achieving their justice aims. They are not allowed to overstep their authority period. When they do overstep their authority, it often harms the State's case against the accused, entirely to make it less desirable for a cop to overstep their authority and protect our rights as people in these lands.
For example, a cop cannot just steal a 3rd party's database to get the evidence they are after. They must either get a warrant or consent from that 3d party, following specific and WELL UNDERSTOOD rules.
You cannot possibly pretend to not know this, so why are you being so disingenuous in your argument?

Except we're talking about the state's own license plate data, not stealing someone else's data. Since it is California's data, California can complain that Oakland police shared it impermissibly. (Good luck with that!) But that doesn't create a constitutional issue.
