According to a ComputerWeekly.com article (via P2pnet.net), some dumbass cop in Japan installed Winny, a P2P application, on his computer, and was unaware of the fact that his computer and anything on it was being shared for one and all to see on the Winny network.
What's the damage? Over 6,600 documents have been compromised including interrogation reports and the locations of automatic license plate readers. It gets worse. The personal information of 12,000 individuals related to criminal investigations has also been compromised.
Oh lordy, it gets a LOT WORSE.
The names, addresses, and personal information of 400 members of the Yamaguchi-gumi, the oldest and largest Yakuza gang have also been compromised. Actually, "gang" is an understatement. The Yamaguchi-gumi are more of an empire, raking in billions in drugs, the sex industry (in Asia, that's saying a lot), stock market manipulation and lots more.
I am not condoning violence towards police, or endorsing organized crime, but considering what this idiot has done, I have a feeling he's not going to be around long enough to collect his unemployment checks.
