Early last year the big domestic infosec story here in Japan was a hacker who was running rings around the police, while making death and bomb threats against airlines and kindergartens.
The Police arrested several suspects - 'extracting' confessions from some of them who later turned out to be victims whose computers had been used by the the hacker via remote access.
The best part of the tale (tail?) is the hacker attached a memory card to the collar of a cat(!) and invited the press to 'play a game' by answering quizzes that led to the cat with the memory card. Possibly the first hack in history to involve a actual cat, and not just LOLcats.exe.
The police eventually captured and charged a new suspect, who is now claiming his innocence and pointing to the previous dubious police investigation (and confession extracting) as proof.
Prosecutors say they found on Katayama’s office computer, searches for the words “cat” and “Enoshima” that predate the email of riddles sent to journalists. But the defense asserts that the real suspect would've planted the searches, recalling the untraceable nature of the virus, which was dispersed widely through the popular online forum, 2channel. The defense, meanwhile, called the allegations “complete nonsense."
Did he do it? Who knows, that's for the lawyers to decide but I hope there's more to the evidence than searching for cats on the internet!

Google has released it's transparency figures for the period January to June 2012 which details requests made by various countries to access user data held by Google. The figures provided by Google only give the total number of requests which (I think) can be a little misleading, I'm no statistician but I thought it might be informative to have a look at the figures relative to population. Other interesting comparisons might relate to law enforcement budget or be somewhat more subjective such as the goverment's stance on data retention.
Australia ranks second behind the US for requests that were complied with when accounting for population, fourth for total requests when accounting for population and ninth for total number of requests.
I think one interesting aspect of the graph below is the discrepancy in certain cases between the number of requests made and the number complied with.
Interestingly, there's a note on the US stats that states:
"Government requests for user data from the United States include those issued by U.S. authorities on behalf of other governments pursuant to mutual legal assistance treaties and other diplomatic mechanisms."
