We don't do the death penalty here because the Bible tells us 'Thou shalt not kill'.
However, we can now extradite him to the US where he is wanted on a variety of charges and let you bunch of godless colonials ignore the word of God and execute him! /humour/
We'll just *redition* him back to Europe for torture, or better yet, send him to "Club Gitmo" for some relief from the stresses of jihad.
LOL.
