Marty,

You continue to completely misconstrue what people are saying, because  
you want to believe this is harmless and is being blown out of  
proportion.

Mr. Kaminsky did not say what you said he said. Not at all.

As for the bad guys not having SSL certs, you're wrong there again.  
Criminals have been known to fool a CA into issuing them a cert for  
someone else's legitimate business. The DNS exploit under discussion  
could even theoretically be used to accomplish this.
