The Death Penalty - are you for or against it and why?

[Thor]

With the technology we have today (forensics, DNA, video cameras, etc...) we can be nearly 100% certain that the accused is guilty. I also support the death penalty to prevent psychopaths from killing again. I know some argue for life without parole. But killers have escaped from prison to kill again. They have also killed prison guards and other inmates. The death penalty is a solution to this problem. Plus, if a killer is in prison for life with no possibility of parole, what do you do if he kills someone while in prison? Give him ANOTHER life sentence?

I think the death penalty should be an option in certain circumstances. Off the top of my head these would include:

1) Murder of a law enforcement officer or prison guard
2) Multiple murders
3) Murdering for hire
4) Murder while committing another felony (robbery, rape, etc.)
5) Murder resulting from a terrorist act

Also, if somone has already committed a crime that will result in life without parole, what does the criminal have to lose by killing some cops in an effort to escape? The sentence will be the same. A death penalty may at least make a criminal think twice about shooting at the police. Not to mention that the prospect of the death penalty can be used by prosecutors to get criminals to talk .
