The problem is selective enforcement. And let's face the truth: most laws are enforced only against minorities, or as someone else put it shortly:
> Conservatism consists of exactly one proposition, to wit: There must be in-groups whom the law protects but does not bind, alongside out-groups whom the law binds but does not protect.
Hell, just look at the marijuana prohibition, it was explicitly done to be able to criminalize lefties and Black persons [1].

So cops are just stopping drivers and giving them warnings. It sounds like harassment to me.
in the case of i stopped you because -rear lights, i see noone else has a notation on your marker, go get it repaired, right now...then your free to go,
thats how i generally see a traffic stop actually being a traffic stop.
Such actions are most emphatically NOT pointless, they are preventative: informing someone that their bad behaviour is noticed is often enough to keep well-meaning citizens on the right side of the law. What's your proposed alternative? That every interaction with the police must result in a fine?
