I just hope the following couldn't / wouldn't ever happen:
There's a grow in a remote area of a National Forest. Forest Service law enforcement puts some hidden cameras up in the area. Someone is there legitimately - camping, hiking, hunting, whatever. The guy gets "caught" on video. A couple days later he's back home and law enforcement bangs on his door. When he answers they treat him like a suspect and interrogate him with a ton of questions, forcing him to explain what he was doing there. If he refuses to answer their questions, they really suspect him, and maybe even take him to their headquarters for further questioning. Maybe he simply thinks that whet he was doing there is none of their business, and he's right - it isn't.
Why should anyone ever be detained or considered suspicious simply because they were seen on a video camera?
I wouldn't be surprised if more than one innocent person has been subjected to visits by the police and questioning because of video cameras used in this manner.
If they need to use cams to try to catch their bad guys, fine - as long as not one innocent person is ever inconvenienced in any way whatsoever.
