I'm sorry I'm late to this discussion, but: some people seem to be saying, "what's the harm? what damage did he suffer?". I'd like to point them to Kyllo -vs- United States http://en.wikipedia.org/wiki/Kyllo_v._United_States http://en.wikipedia.org/wiki/Kyllo_v._United_States . Basically, the USSC ruled that taking a thermal image of a house amounted to "unreasonable search". Even though the heat rays emanating from the dwelling can be considered "public knowledge", the cops can't use it to then conclude that there's a grow op in the house. So, just because something is sorta "public" it doesn't mean the cops can reach for it.
