Very true, but it helps in debate if you can back up the argument on specifics.
For example, here it can be proven that the death penalty is more expensive; independant research from numerous sources can back this up, therefore it's impossible to argue that this point isn't true no matter what the morality issues.
In this particular part, it's hard to argue that a life term in prison is more expensive when reading a few articles will show you otherwise... I'm not saying facts are a 100% necessity, but handy if you don't want to go making a blind denial of something and not be able to support your argument surely..?
As for the death penalty, well while morally I'm against it and believe it's wrong, I can still see it being applicable in extreme cases with overwhelming evidence against the person in question. I can morally be against it one hundred percent, but that doesn't mean I can't see the POV and accept that of those who support it and, in the extreme cases, act on it. If that makes any kind of sense...
