yes, Karl's name will most likely pop up if he tries to look for it in the internet but you need to understand that Ryuuji is inherently an untrusting person. Lets admit it, even in current real life, if you got an email from a complete stranger with no previous contact with, you'd more likely to be suspicious of the person or even chuck the mail straight to the junk mail folder than flat out accepting their explanation.<br/><br/>In Ryuuji's case, rather than just running through search engine looking for his name, he's rather ask one of his trusted subordinate to look it up at official record and confirm that Karl is who he said he is, that is his modus of operation. THAT and he hasn't even got the chance to do it, as far as Ryuuji is concerned, what happening in his turf is far more important than something that happen halfway around the world.
