Watching children play with random garbage found on the side of the road (and their parents futilely trying to stop them), the following question came to my mind:
If you pick up a piece of garbage, examine it, and then put it back on the ground, do you violate any littering laws?
In other words, do you, by touching the garbage, somehow become "responsible" for disposing it? In the example situation above: Can the parents tell the kids to just put the trash back where they found it, or do they need to carry it with them until they find a trash can?
This is a purely hypothetical question out of curiosity, so answers for any jurisdiction (that has laws against littering) are fine.
