Personally, I feel this was the sleaziest tactic the defense engaged in. And JB can pass it off as his own idea, but I doubt it - he hasn't done much of anything of substance the past year - this came out when AL and her sidekick came into the picture.
It was sleazy because they didn't interview this woman under oath and submit it as discovery, which would have allowed the state to respond and verify it as true or to investigate it on their own before it was displayed to the public through the media. This "interview" was heavily edited and attached to a motion - like some sneaky barnacle of an addendum to a bill in government - so that it could circumvent the normal procedure of the Sunshine Law in FL and pretty much go directly to the media and thereby influence the public. Anyone who knows anything about manipulating the media is aware that if an audience sees a picture of something it doesn't matter how many times it is retracted later, the first visual impression stays with the audience as truth.
To have completely bypassed normal procedure and slapped lipstick on this slanderous pig of an "interview" and palmed off her allegations as evidence to the general public (which may not understand the distinction between a youtube-y type video and an actual sworn statement) is not just unethical, it should be criminal.
To add insult to injury, the defense then delayed as long as possible in making the state aware of this woman's contact information, so they had little chance of following up until she might be too ill to be correctly deposed.
I hope this whole thing backfires on them. If JK is unable to give a proper deposition due to illness, or if her treatment interferes with her ability - then the entire thing can be thrown out as inadmissible. If not, then she can appear and let the state verify the validity of her claims. Making a very ill woman your star witness and delaying her access to the opposition is just junk lawyering, imo.
However, even if things go well for this woman, and I hope she comes through her treatment - I have trouble thinking her testimony will be all that credible. She has her own sketchy history and past which I'm sure will mitigate any story she feels she needs to tell.
One thing we know is, many many people can substantiate the lies and criminal acts of KC - including but not limited to a family that never reported them. If all that stands against RK's reputation is a disgruntled ex and her daughter, I don't think it will stick.
Frankly, as hinky as people find the whole RK story, I think the fact that RK's family did a 180 on their initial reactions to him (some on paper) after he found Caylee's remains and suddenly popped up as defense witnesses, is just as bizarre, if not more so. It smacks of outside influence if you ask me.
