Tsarnaev Sentenced To Death

I just finished reading all the stories about how the jury found him guilty and what disturbs me the most is not that this psychotic douche-bag muzzie scum licker is going to die someday.....but that the jury seemed to have such a hard time coming to this conclusion. He admitted it, he's on film doing it....he had that crazy assed manifesto he drew in blood....why the questions?
