From the story:
_The incident has set off a debate about privacy in Austria and whether wildlife cameras should be allowed to operate unmarked. One data-protection activist says the cameras pose a threat to people's rights. The cameras should "at least be marked with signs," Hans Zeger, head of ARGE Daten, an NGO focused on data protection, told Der Spiegel. This would enable people in the forest to "adjust their behavior and avoid the monitored areas."
It's worth noting that the area into which our amorous Austrian and his lady friend wandered was marked with no trespassing signs, so maybe his activities were, shall we say, fair game. But what do you think about trail cams on public land? Should they be marked? Are they required to be flagged or marked in your state? Or would doing so only insure that you'd lose a trail cam. Is there an expectation of privacy in the woods, or does it behoove you to keep your pants on?
