Not to get political, but as somebody who worked in the business for a state for 30 years: this is what you get when a state feeds from the Federal Trough.
There is federal money out there to be had, and some dweeb in HQ (who's job is to get it) made use of it. The result is some guys (road officers, aka "taillight chasers") can get in some overtime and take home a few extra dollars for groceries. If a guy can pick up an extra $1000 per year from the feds, maybe it keeps them happy with the state and on the reservation.
We used to have to use a vacation day to pull a shift that was paid for by the feds for a "special enforcement program" such as this, and although it was straight pay, the state got rid of a vacation day on the books, and the officer traded his day off for some money paid for by the feds. Then the guys got wise and said nope. So they let them work overtime at straight pay, coming from the fed coffers. There's "special truck enforcement", "special speed enforcement", "special seat belt enforcement", looking for drug mules, etc. all federally funded.
Bottom line is they probably don't have a hard-on for motorcyclists, and while I'd be willing to bet they won't be throwing any drunks back that they find, they are just making use of a chance to make a few extra bucks. I doubt that any are being forced to do the duty, they volunteered for it. Down side is, I bet somebody's shift is going to be short handed and his ass is out there alone tonight because the rest of the zone just worked the day shift screwing with the bikers.
Don't take it personal.... most of the guys on the details would rather be doing what they signed on for-- at least the older ones. But as they say money talks and ******** walks.
