As nasty as you seem to have gotten, bunnyp, I will answer your questions.
1. The PI, Casey, was working with for the Anthonys at the time the tape was made. Of course, PI Casey wasn't lying, Hoover wasn't employeed by his firm. Why would he lie about that, it is easily proved one way or another.
2. Hoover volunteered to work FOR the Anthonys, there's no such thing as his "own time", the work product in relation to the case, belongs to the Anthonys.
3. This is not evidence of anything, it is not subject to the Judge's order, because Casey was NOT working for JB at the time the tape was made. Of course, JB asked that a master be appointed at any questioning of the PI, whether he was working for the client or not - the questioning COULD involve work product belongin to his client, KC - NO attorney would allow an employee directly employed or employed by contract to be questioned about the case without either his presence or the presence of an attorney. (FYI, the privilege belongs to the client, not the attorney, it is the attorney's duty and responsibility to protect that privilege.) And no, we don't know if this was in the exact area, a foot away or a mile away, we have no proof that the tape was made for any reason, other than to record a man shoving a stick into the ground. We can speculate, we can surmise, we can wonder, but this tape is absolutely worthless as evidence.
Now, if LE had confiscated the tape last week from Hoover, where and how did the Anthonys get a copy of it to release to the media?
