Reading things like these in other (even developed, Western) nations: - UK surveillance state powers, anti-porn laws - Australian laws to detain you, break encryption - This German incident I sure am glad to live in a country where freedoms are explicitly guaranteed by a constitutional decree.
I have to think that officials are hesitant to engage in many of the petty tyranny we see in other western countries, however, at a rate proportional to the degree to which their constituents are armed. If a police raid has a non trivial chance of turning into a shootout, it's a tool frequently withheld, and probably never used over a tweet.
The wrongful death process in civil courts would also destroy the life of any official who provoked a deadly raid over social media.
