When cars are stopped at a DUI checkpoint, the vast majority of the drivers haven't done anything wrong, and there's no reason to suspect any of them have done anything wrong. Nonetheless, such stops have been upheld as "reasonable". From Wikipedia[1], > The Supreme Court held that Michigan had a "substantial government interest" to advance in stopping drunk driving, and that this technique was rationally related to achieving that goal (though there was some evidence to the contrary). The Court also held that the impact on drivers, such as in delaying them from reaching their destination, was negligible, and that the brief questioning to gain "reasonable suspicion" similarly had a negligible impact on the drivers' Fourth Amendment right from unreasonable search (implying that any more detailed or invasive searches would be treated differently). Applying a balancing test, then, the Court found that the Constitutionality of the search tilted in favor of the government. Assuming one agrees with that ruling, I'm not seeing how chalking cars isn't a sufficiently minimal "reasonable" search to allow the government to enforce things it has an interest in. (Assuming also that parking enforcement qualifies as a "substantial government interest" — which, IDK, perhaps it doesn't.)
