Kidnapping and robbing in Islam

[Bittersteel]

Why would anyone think it supriseing that this kidnapper is not going to be prosecuted. The Koran preaches that this is legitamate. The women kidnapped are lucky that they still have there heads. According to the Koran these women are infidels and anyone who is familar with the koran knows what muslims are to do with infidels. It is a lie that people like Osama Bin Laden have hijacked Islam. Osama Bin Laden is a good muslim doing what the Koran teaches him to do. People need to study Koran

was just browsing through jerusalem Post and this caught my eye.
I don't know where he got the whole idea from,but what does the Quran say about kidnapping and robbing?is it permissible in some exceptional cases like in times of war?
please help.
