I do support it, but there are too many problems with it. In cases where there is absolutely no doubt about guilt, "FINISH THEM!" There are far too many cases that have been wrongful convictions and put to death. What do we say to those people and their families? OOPS?!
I knew a woman that was murdered in the city of Rochester in November of 1995. She was raped, beaten and then she was bound and strangled with her own shoe laces. Both perpetrators left DNA evidence behind and were convicted on that evidence. They were both suspects right from the start, but the DNA sealed their fate 12 years later. Both of them should've gotten the death sentence IMO. If I could, I'd start the lethal injection process, but I'd be in a long line of family members willing to do that. Howard Wright and Christopher Gifford are their names. What do we do with garbage? We throw it away to decay in a landfill. We don't put it on ice in the hope that someday it will be fresh again.
