Yep, they do that here too. (: Although one can, if one is a teacher of said language, teach the language to various groups inside the said organisation. However I'm betting, as you did, they would actually try and hire someone a bit saner. You know. Like a teacher, rather than a random psycho. It's not that uncommon to speak a foreign language... it's not like he's the only one who can teach Sumerian to the poor lads. And what fun that could be!

Hm, although I'm speculating LKH would rebut all our concerns with 'But they're terrorists. They kill people. Olaf kills people. Do you not see the connection?! HAVE YOU NOT READ THE CALENDAR?'
