Yeah they hired the PI's to look for a dead or alive Caylee. And that is why they tried to interrupt the search at the park, because they thought she could be dead. Actually, they could be telling the truth. While they were saying in public that Caylee was alive, the PI's could have been hired to find the dump site and make sure it was clean!
What the A's said in public certainly points to what they were doing, but what they said in public is not what charges will be filed on. What they said to LE and their actions is what will get charges filed on. And after the recent video, I am thinking the charges might be stronger than OJ. I am wondering if this is enough to get them charged with accessory after the fact.
If I am right then someone may get immunity. But it will probably be JH, and maybe DC. They were just hired hands. The people that gave them orders is who will get the charges.
