It may seem odd that so many people would support the death penalty while also acknowledging that innocent people could very well be put to death. Part of that may be accepting the inherent risk that accompanies something as irreversible as death, but a part of it may also simply be that people are not paying that much attention to capital punishment. Executions in this country are generally carried out at night inside heavily guarded prisons with just a small handful of witnesses, so the public rarely takes note of them.
