Let's hope they do. I'll be curious to see how he is ultimately punished. And how folks react to the news of his confession. Here in the States, I've heard that some UK folks who have lived among the Muslim immigrants and citizens so long and peacefully, are in denial about the intent of the terrorists. (Of course, we have that here, too...)
The liberal elitists at the EU are probably coming out saying that killing him would be contrary to "EU morals".
They keep saying that when Poland talks about executing criminals like this.
