Interesting topic here. Haven't heard too much about it. Will look into it in the morning.
However, my thoughts on the death penalty: Simply put, it doesn't work. Using the US as an example, recidivism rates are higher in states which do have the death penalty which goes to show it doesn't do much to deter crimes. Strictly speaking from statistics, I'd rather see it done away with completely and have more money dumped into rehabilitating (probably not the right word to use in this instance, but whatever) offenders, getting them further education and real life skills to help set them up for when their time has been served. From a more personal, emotional side of things, there are certain crimes where I'd love to see the death penalty. Things like sex offences, pedophiles, etc. I realize there are other factors there, and it's more of a psychiatric thing, but again, emotions cloud logic when I hear about that in the news.
More specific to this case, I see it on both sides of the coin. And I'm assuming extradition isn't applicable in this scenario? For the first viewpoint, the crime was committed in a foreign country, so in a way, the country has somewhat of a right to sentence them. However, I feel like it's always better to have their home country be the ones who administer the justice. However, it seems like there's not a shot in hell that's going to happen
