I think you missed the point.Please define "successful outcome".
Perhaps driver gets a citation after a random check, thereby earning a little revenue?
Perhaps driver has a large amount of cash on hand, thereby earning a lot of revenue?
Perhaps driver has no violation, is handed back his documents, and told to "have a safe trip". (driver leaves, relieved to not be in trouble, possibly aware that something's not right about a free American submitting to a checkpoint)
A successful outcome would be no check point to begin with, and thus no crazy man pulling his gun for an irrational stop.
This is not an anti-LEO position, either. The problems tend to go higher up on the CoC.
