Do you think casey anthony should be punished?

i am so disgusted with her and her family. even if whatever happened to that poor little girl was an accident, there was so many lies and why couldnt we get the truth? did they not care about finding her or getting justice for her? if someone else killed her then why is the family not interested in finding the real murderer? and why would their computer show someone looking up that chemical more than 236 times, the same chemical used on caylee, if they are innocent? i dont know if it was the mom, dad or casey, but either way the mother deserves to be in prison and die there. she seems to have no remorce. if i was innocent i know id be frantic searching for the murderer, and i wouldnt be able to laugh or smile like casey often does. id be the most saddened mother you ever saw. i just cant believe shes walking free after all this. absolutely disgusting.
