Myster aeound Caylee Anthony death

The mother got a not guilty on the basis of no information from the Child's death. And of course the person with the knowledge supposedly kept her mouth shut. The next question did they ever find the missing body. I guess not or she would not be declared inocent . I guess it was due to lack of knowldege as what happened to the little girl.
lI have a question and that is simply do the police and DA's office really investigate these crimes. I always looks to me like they just try to find somebody guilty with out any real investigation as to who is really guilty. I remember reading about those cases in Chicas where these young lawyers investigate the people on Death row. and according to their findings quite afew of these people were inocent of the crimes that were committed. At least they got pardoned of those crimes. It seems like if the people that are convicted of these crimes do not plead gulty then the people that look into these crimes really do not know what they are doing. Maybe there is not an answer as to who are commiting these crimes and do not plead guilty then there is not a way of provisubg unless the come forth and admitting their guilt. These are questions that bother me about these cases. I rmember as a kid- these people not try to convict these many people and our prisons were not full until; Politics made that possible. Again if the person is convicted then at the end of their sentence then they also be allowed to restart their lives and become normal citizens and according the Western Stores- they even became Law Envorcent officeers and did a great job and with their experience- even knew what they were doing. Any thing would be better than the system that we have now.
