I would have had CA handcuffed and shackled ages ago, but that's just me.
I know publicly GA has done his share of obstruction, but privately he actually did advance the investigation. Obviously he was publicly following CA's orders.
While LA pretends to be helping with the investigation and cooperating with authorities, it's obvious to me and to his attorney that he was in jeopardy of charges, thus, his "cooperation" with the ZFG deposition. There must be more hidden to us that LE/SA isn't saying, but obviously his attorney knows what's going on.
If anyone thinks there is no evidence against CA, you haven't been following the case. Nearly every public interview, TV appearance, public appearance, and LE/FBI interview screams obstruction. Sure, she was a grieving grandma/mother trying to keep going, but she forgot about the victim and protected the guilty. She lied, held back evidence, purported KC's concocted stories as truth, and blasted LE for doing their job. Her refusal to be forthcoming was a slap in Caylee's lovely little face. Plus, she had a private investigator out searching the woods where Caylee was eventually found! Did she know something? Was she planning to hide the remains if found?
They are probably waiting until all the ZG depositions are complete and waiting for Casey's trial and conviction before moving forward, unless there is some sort of statute of limitations where they must do it sooner. If any of them are charged now, would they be allowed to take the 5th when being questioned in KC's trial because it may incriminate them and hang them in their own charges? I don't know. I really wasn't expecting any charges this soon or so far off from KC's trial.
If KC is acquitted (oh, please, no!) there will probably be no charges filed for any of the As.
It's been so long since I took law courses in college, I can't recall all the tiny details, but I didn't study the Florida law system anyway.
