Aldaron, good point, but judging by the trap and the set, I would say that something the size of a cougar/wolf/bear was the intended target. I doubt these guys actually set the trap. The circumstances of the trap being set at all is interesting. Not knowing in which state this occurred, I do not know if they have a cougar trapping season or not, but if they do not, then someone was possibly breaking the law. I have never heard of a "cougar trapping season" but I do know that some states do things their own way.
One scenario is something illicit. Why? Primarily because no agency employee (as part of their job) traps large predators just to risk their life letting them go. If this was a legal incidence of trapping a cougar, then the folks that let it go violated the law. Even if the intended target was another large predator, many agency personnel would leave it for the trapper to take care of or put the animal down rather than risk themselves to set it free. Maybe someone reported a trapped cougar and these 2 guys were the closest agency reps to the site. I have no idea and there are other possible circumstances but I do not want to go down that rabbit hole.
But, if part of my job had the potential to handle trapped (or otherwise) large predators, I can guarantee you that after the proper training, a drug kit would go out in the field with me every day.
Anyway, I'd love to hear more on the circumstance surrounding this event, just for curiosity's sake. These guys were obviously trying to help it and succeeded so big kudos to them for that. There's just safer ways (for all involved) to go about it.
