Here are some blog posts on the repression in Latvia, a number quoting publications already noted here.
Marathon Pundit ( a US political blogger whose wife, it appears, is from Latvia).
The Bruges Group Blog (a rather long post, quotes the Wall Street Journal)
The Fundmastery Blog (on investing/?/) also quotes the WSJ)
Mostly Economics (a blog focussed on India, but free speech matters)
The Mises Economics Blog (free market economics)
Dispatches (another blogger with some link to Latvia)
UK Top Secret (another personal blog)
The sad thing is that the provincial, narrow-minded, inferiority-complexed (deservedly?) people in the Latvian government who approved this operation as well as those in the Saeima (parliament) who think this is OK are unlikely to read any of this, even to be aware of this. Basically, these authoritarian boors don't give a flying f**k what the outside world thinks of them.
