I had the pleasure of quail hunting with two retired New Mexico game wardens for about 5 or 6 years in a row. Plus we did a couple of deer hunting trips together. I heard a lot of stories about other game wardens and about the two I knew.
Here's one that was described to me as an example of "discretion".
Two wardens, one new, the other an old salt, were working the mountain country of northern NM one night and got into a high speed chase with a truck that was spot-lighting and poaching.
They chased the pickup all the way into an encampment of about thirty local residents who were having a large bonfire/drink-fest. The truck "people" bailed out of the truck and ran through the party and out the back side.
As the young warden jumped out of the car to "give chase" the older warden told him to get back into the car. A short argument ensued with the younger man accusing the older man of cowardice. The older warden told his accomplice to take note of the partygoers...a lot of them were wearing handguns and all of them had been drinking for a long time.
So the older, experienced warden told the younger one to disarm himself and "follow me".
The older warden then went into the crowd and walked up to the local judge, who was there with a lot of his relatives. He said a friendly "howdy" and then began a coversation with the judge that went something like this:
"Now you know as well as I do that those boys were poaching. How about if you have them in your chambers on Monday morning and I'll come over and we'll talk about this?"
It was done. The driver of the pickup in question was a nephew of the judge. With the warden present he was given a light sentence and a serious butt-chewing by the judge.
I get the impression many LEO's today are not taught much about "discretion" and taught more about "backup" and being in "control".
I just followed this thread and the original with "wickahoney"'s reporting. Very interesting. It appears one officer back then lacked a LOT of discretion.
