Yeah right blame filesharing

THats like saying that if he had written them down on a bit of paper and left it in a bus shelter, its the paper and pen's fault.

No, the guy broke company rules to install the software (presumably Soulseek or soemthing similar) and also was num-nut enough to share a directory containing sensitive information.

Sack the guy - its his fault, not P2Ps, he shouldn't be allowed access to such information if he can't look after it. End of story.
