Dylann Roof found guilty - rot in hell

And, can you guarantee that in the approximately 15 years Roof will spend on death row, he won’t kill anyone?

From the wiki article on Death Row

In the United States, prisoners may wait many years before execution can be carried out due to the complex and time-consuming appeals procedures mandated in the jurisdiction. The time between sentencing and execution has increased relatively steadily between 1977 and 2010, including a 22% jump between 1989 and 1990 and a similar jump between 2008 and 2009. In 2010, a death row inmate waited an average of 178 months (roughly 15 years) between sentencing and execution.[1] Nearly a quarter of inmates on death row in the U.S. die of natural causes while awaiting execution.[2]

So it’s a death sentence, but for a quarter of the people sentenced to death, it’s life in prison without parole.
