Does the money for the 'texting while driving' fine go to the county or the state? It's a very important question.
Back when not wearing your seatbelt was a secondary offense (they couldn't pull you over for it but they could tack it onto another violation) a certain state had a record of dismissing the primary violation (money went to the state) while keeping the secondary (money went to the county). Revenue stream pure and simple.
There's such a thing as giving a warning. Texting at a red light isn't the brightest thing to do but it's also way down on the list of stupid things to do. The officer camping out at the intersection just waiting to pounce on these drivers isn't looking for the dangerous offenses, he's looking for the ones that make him feel important and show his authority to "those scofflaws".
Stick him on patrol duty somewhere out in the boonies on third shift for a few years and let him find ways to hassle people there.
