Wa 'alaikumu as-salam wa rahmatu Allahi wa barakatuh It would be similar but different. I don't think the Muslim would have necessarily been thought of as insane, which is a positive depending on how you think of this. Breivik dreaded being deemed a psycho. He didn't want to be seen as insane because that would damage his cause in his mind. People don't want to be deemed as nutjobs. Breivik was happy not to be declared insane! Most of Breivik's trial was about whether he was insane or not. Being declared insane is humiliating. The fact is Breivik has caused damage to people like him in Norway. It threw his ideology in bad light. I don't think the sentence would be that different. A Muslim would most likely get life, which Breivik has also got in practice. I don't think the Norwegian goverment is going to let him out after this fiasco. Have you followed this case? There was a big investagation into the police response. It found that this thing could have been prevented better handled. It was found to be inadequate. The Primime Minister said he, as the country's head, had to take the blame for the delayed response. An absolute fiasco which they don't want to relive. Quite frankly, I don't know if a Muslim would have gotten a mattress as soft as Breivik's with absolute certainty. But since there is no evidence that Muslims receive poorer facilities in Norwegian prisons, I will assume that he would have seeing that Norway is very liberal. If a Muslim had done this, I would want him behind bars just like Breivik. It does not matter whether it is Breivik or a Muslim. The only problem if it was a Muslim, would have been the backlash against the Muslims and Islam. That is very dreadful and hateful to me. In summary, it would have been quite similar but slightly different, not much in practice. And Allahs knows best.
