The roadside in our semi-rural area is relatively litter free. With very few exceptions, it can be easily picked up with one hand, and is not gross.
But one litterer is getting to me. He (or she) tosses out V8 juice cans (tangy) with depressing regularity over a 300 or so foot stretch across the road from my neighbor's property. This probably happens in the morning.
There is a good, and comfortable, lookout point on my neighbor's property which commands the entire stretch, and more, of V8-Juice-Guy's littering. I have seriously considered sitting there with a camera and catching V8JG in the act. With her permission, of course.
Drawbacks to this plan: (1) I'd have to get up too early; (2) crushing boredom and (3) ticks.
Now I wonder if a trail camera or a similar camera could do the work. The camera would have to capture the scene in daylight and give enough detail to get the license plate of a car going at 30 to 50 miles per hour. (50 mph would be reckless on our road, but some people are reckless.) And clearly identify the act of tossing out the V8 juice can with the specific car. There is not much traffic on our road.
As to what I would do with the information if I got it: I am not sure. There are obvious downsides to doing anything. However, people have jumped to the conclusion, without any evidence in this question -- in fact, with evidence to the contrary in this question -- that I will use the information to get embroiled in a time-consuming and thoroughly unpleasant criminal prosecution or civil suit. I repeat: I haven't decided what I would do with the info, if anything. The intelligent first step is to write the litterer a polite letter asking him to stop. But, as I said in the original version of this question, I don't want to discuss my options until/if I get the information. Please confine answers to how I can get the information with an automated set-up.
Addendum on Legal Issue: Littering is illegal in Virginia. Source: Code of Virginia 33.1-346. As for whether photographing a litterer in the act is itself illegal, I will get advice from the Fairfax County (VA) Police if I decide to go forward.
