How exactly do tag readers violate any constitutional provisions?
How much information about somebody can be had from running a simple license plate??
Who has access to this information and why?
If there is no probable cause for them to be asking for this information, than they should NOT have access to it, any of it.
An auto mated plate reader does all of this. This is akin to walking in the park minding your own business and a cop stops you and starts asking you for identifying information. Driver's License? Gun Regsitration cards.. proff of insurance.. and having the ability to arrest you and fine you on the spot for any infraction he may find by pure happenstance.
It's not legal to do it person to person it should not be legal to do by "plate reader".
