I slightly oppose. In Countries that support capital punishment, crime rates tend to be higher then average. I don't feel that it would solve any problems. Unless someone truly deserves it, and is guilty beyond any possible doubt. And by truly deserves it, I mean some sort of serial killer or the likes. I'd say that overall, the jail system that is around right now (in Canada at least) is fairly effective. I occasionally hear about someone thats a repeat offender after being "remediated", but 99% of the time people that are released from jail won't commit another crime.
