I am split on the issue. When I am thinking about this in general (i.e. not tied to any particular case), I am against the death penalty but I must admit there are cases where in that particular case I would not be against it, but that is my emotional side speaking.
My issue with the death penalty are:
- to me it seems to be more about revenge than anything else. While this is understandable on a personal level, especially for those affected by the crime (and I would be no different), the justice system should be as free from vengeful emotion as possible.
- the death penalty is final, so in case an innocent person has been executed there is no way to make this right - and there have been (far too) many cases where innocent people were sentenced to death based on sloppy investigating, ulterior motives, giving wrong testimony, hiding / manipulation of evidence, people not doing their job properly...
- In many cases a death sentence is actually a double-punishment since convicts can sit in jail for 10+ years before the sentence is carried out.
So, from the above, if society feels that the death penalty should be allowed, then
- it needs to be ensured that all defendants have a proper legal representation
- there need to be certain requirements on proof (i.e. the smoking gun)
- it should be swift (no combination of a long prison term and an execution)
- it should also mean that anyone contributing to an innocent person being executed (i.e. because they were hiding, manipulating or ignoring exonerating evidence) should automatically receive the same sentence
