So what is wrong with photographing an area? I would imagine that Casey has taken photographs of just about all the areas mentioned in this case. I'm sure he's taken photos of Fusian, of AL's apt, "Zani's" apt, Blanchard Park, every room in the Anthonys' house, has or has tried to get statements from every single person whose name was mentioned regarding this case and has talked to most of their neighbors. The reason they do this is because it is their job to do this. No attorney wants to be surprised with evidence he hasn't seen and every defense attorney will make an effort to get a statement from a potential witness to prepare a line of questioning.
You know, this is exactly why I despise the rumour mongerers and gossips who throw out ungrounded allegations and accusations against people who are doing their jobs. When you do something like that in a public venue, you are ruining careers and curtailing people from making their living. It is wrong, it is unethical and it is immoral to make public allegations for which you have no proof.
