Final answer:
The statement addresses the belief held by some, including law enforcement, that Wayne Williams, while convicted for two adult murders, may not be guilty of the Atlanta Child Murders. There are differing opinions on his guilt.
Step-by-step explanation:
The statement in question is: Some even inside law enforcement, however, think Wayne is innocent or at least not guilty of all the child killings (he was only convicted of killing 2 young adult males). This statement appears to refer to Wayne Williams, who is a convicted murderer suspected of being responsible for the Atlanta Child Murders during 1979-1981. Although Wayne was convicted for the murder of two adults, doubts about his involvement in all of the child murders have been raised by some, including those within law enforcement circles. It's important to note that these views aren't universally accepted and there is significant evidence against Wayne Williams for these crimes, although he has not been tried and convicted for the child murders specifically.
