Various Ways the Anthonys Have Obstructed Justice

Cindy febreezed the KC's vehicle

E-mails from Cindy's account to various media allegedly not sent by Cindy but such "hacking" incident was not reported

Cindy spoke to tow guy (alleged attempted "intimidation of witness")

George told FBI he would get them EZ-Pass records and never produced and possibly lied about the KC car chase

Cindy took cash from items retrieved from Tony Lazarro's apt. and Lee alone with KC's belongings from TL's apt. alleging that lap top may have been tampered with from someone in TL's apt because of blue screen

Oh good ones, Sus. And Lee took receipts out of Casey's purse, didn't he? After Cindy rummaged through Casey's wallet and stole back the money.

Shouldn't all of those things have been turned over to LE immediately?

Yes! All of the items found at TL's apartment should have turned over to LE but the Anthonys maintain that the police officer who was at the house at the time let them rummage through KC's belongings and take the items they wanted (cash, credit cards, receipts).

Also I remember that LE originally asked Cindy to bring in the washed pants and in a later interview mention to George that Cindy said she's bring the washed pants to them but never did so LE had to obtain them through a search warrant.

The biggest obstruction of all is that each and every one of them has made this case all about themselves, individually, and taken the focus away from truth and finding justice for Caylee's murder.
IMO

Another big one for me is that none of the Anthonys told LE or FBI about the huge fight of 6/15 that we know from other sources did occur
