Here's a little thing folks don't know. For an Forest Service LEO to site someone, that LEO or another Forest Protection Officer (FPO) needs to see people at the dispersed site each and everyday and have it documented. To be an FPO all you need to do is take a 3 day training course. These folks can only site folks for minor things, but they can act as a witness for the LEO. FPOs normally have another duty on the forest, but hold the qualification incase they see something that needs sited or educated. The key is 14 consecutive days. If one of those days is missed, the clock starts over. The reason for all of this is really about the folks who live on the forest, but the rules apply to real campers/hunters as well. If an LEO goes to court and can't prove the person was there for 14 consecutive days, then it gets thrown out. That is why an LEO rarely wastes their time on this kind of thing. They will make contact and can educate the campers. Many will actually leave once that contact is made. That said. When push comes to shove, the LEO knows he needs to prove the 14 consecutive days, which is almost impossible to do with the lack of staffing.
One LEO can be responsible for several districts and even more than one National Forest. Oh and they can often be called out to assist other Federal Law Enforcement, because their training allows them to respond and assist with everything under the sun. Many days go by with zero LEOs available to a district or Forest. Then it falls on local law enforcement or state police. They will only assist will actual crimes or serious incidents. It's sad and something that isn't given enough attention when it comes to funding public lands. We need more LEOs.
