Reasonable Doubt

As an ID 'addict', I may be biased but 'Reasonable Doubt' is one of ID's better shows. Both Melissa and Chris are very professional, courteous, and seem totally unbiased. I'm curious to know how the producers are choosing these cases. As it seems the show is relying on communication from family and friends of convicted murderers, who obviously believe in their loved ones' innocence. However, everyone is capable of killing someone! No exceptions! Despite alleged errors in an investigation or a trial, people need to understand and accept that there is no human incapable of killing. Melissa and Chris show all sides of these cases and I don't understand how anyone can disagree with their findings. Good production!
