In my hometown they set up a monthly DUI roadblock. They catch about 3 DUIs, but incidentally stop another 290-300 people on other non-DUI offenses. The cash cow is the other people and we earn garner hundreds of thousands this way.
Now, what is happening to the other DUIs during the other 28, 29, or 30 days a month. Nothing.
It is a cover story for the tax collectors. Our police forces are essentially meter maids for the welfare state.
I mean, when we catch them the “normal” way. I’m not a big fan of road blocks.
