What I Don't Understand About Anthony Family

I don't understand how the family of Caylee Anthony is why they aren't looking for her harder. My oldest son was lost by his school in middle school. The sheriff's office had the helicopter looking for him in less than an hour. I made almost made the teacher in charge of him cry. If they had reported Caylee missing immediately the police would have pulled out all the steps to find a two year old. They are covering up something.
