Had something like that happen to us on a hike. We were in the Talladega National Forest and had pitched our tents next to Morgan Lake after hiking 14 miles through mountainous terrain. We were dead tired and wanted nothing more than sleep. We went down around 7:00 PM, after dark, next to a gravel drive for the lake. This is a small lake with only one access and no facilities other than the gravel path. We arrived before dark, say 5:00 PM, and were bedded down as I said around 7:00 PM in two tents, four guys, and two dogs.
At some point we heard some vehicles driving up. Roused, I sat up in my tent and looked at my roomie and asked the time, wondering why anyone would come out to the lake at that terrible hour (thinking it was somewhere around 3:00AM). It turned out it was only 9:00PM. At that moment, red and blue lights began to spin and a spotlight was pointed to our tents (actually two lights from two different cruisers). At that point, we heard a gruff voice call out to us that they had a report that people were doing drugs out at the lake. There was no truth at all to that lie as nobody had come out to the secluded lake since we arrived and we had been there for four hours. Well, my dog was trying to poke her head through the tent door while I was trying to get out of my sleeping bag when the voice said "you better come out now." I yelled out that I was getting out of my sleeping bag and trying to pull my dog away from the tent flap (didn't want my collie to get shot). I poked my head out and said we were not doing drugs, that we had hiked 14 miles that day and had left a Jeep Cherokee parked at a trail head on another highway. I told him that nobody had driven there since we had arrived and that all we wanted to do was go to sleep because our pickup location was sill 30 miles away.
At that point, my friend who was getting impatient called from the other tent "They can take me in if they want, I'll get to sleep on a bed in a heated room." I groaned and looked up at the blinding light (looking stoned, I'm sure, after having been wakened from 2 hours sleep and squinting like I ate a lemon into the light). They turned their lights off and without a word drove away. I hate when LEO's blatantly lie. There was absolutely no way anyone had seen us to report anything. Nobody had driven up and we were miles away from any houses. What they were doing there I could not say, but there was no need to lie to us. They could have easily asked what we were doing and we would have told them no problem. We did tell them, the accusation that we were doing something illegal was uncalled for.
