Second question first yes, to a point. Next, Why Moroccans? Well, because the islamist movement despises the King and the kingdom and their relatively free society. Secondly, they probably have turned Surete National loose on the beards , and God help them because their interrogators won't. Personal incident, I had a beard on a bus start up on me last week. The other passengers shut him down and made him get back to his seat. Maybe they were just being polite to the American on the bus, but they made sure this clown understood his outburst was unwelcome. So, yeah, I am angry about this attack and I think that whomever the bomber's associates are, they will soon be a were.
Morocco was a wonderful place then. I often wonder what it's like today.
