Lots of information here regarding capital punishment in the United States today. From the DPIC statistics, consider the following:

• Since 1973, more than 155 people have been released from death row with evidence of their innocence.
• Florida had the second highest death row population in the country, exceeded only by California, in October 2016.
• Enforcing the death penalty costs Florida $51,000,000 MORE each year than if these 1st degree murder convictions had been given a sentence of with life without parole.
• The South has the highest murder rate and over 80% of executions are performed in the South.
• As of January 1, 2015, there were 56 women on death row in the United States.  No juveniles are on death row because capital crimes committed by juveniles cannot be given the death penalty according to a 2005 SCOTUS decision.
