Do you support capital punishment?

[Grizzly]

Can you kill someone who pleaded guilty?
What if they have a mental illness? (I mean, anyone who could rape an innocent young girl must)
How can you be sure you have arrested/will kill the right person?
Can people be killed for murder if it was a crime of passion? (Eg. walk in on your wife with another man and kill him.)

1. Normally not, that's how many people avoid the death penalty. When you plea guilty, there is usually some sort of plea agreement. Usually life in prison instead of death.
2. There is only one legal insanity plea (at least in Tx) and that is you did not know what you were doing was actually wrong.
3. I believe unless their is DNA evidence, then life in prison without the possibility of parole is a much better option.
4. In most states, there are laws surrounding crimes of passion. In the state of Texas you have a roughly 3 hour period from time of discovery until the act occurs for it to be considered a crime of passion and you usually will not be indicted.
